How to clean the head of lice at home?

Understanding Head Lice

What are Head Lice?

Head lice, scientifically known as Pediculus humanus capitis, are obligate ectoparasites that inhabit the human scalp. Adult insects measure 2–4 mm, possess six legs, and cling to hair shafts near the scalp.

Key characteristics include:

Flattened body adapted for navigating hair.
Claws on each leg for gripping strands.
Ability to survive off‑host for up to 48 hours under favorable conditions.

The life cycle comprises three stages: egg (nit), nymph, and adult. Eggs are attached to the hair shaft with a cementing substance and hatch in 7–10 days. Nymphs undergo three molts over approximately 9 days before reaching maturity, after which females lay 6–10 eggs daily.

Infestation manifests as:

Persistent itching caused by allergic reaction to saliva.
Visible nits within 1 mm of the scalp.
Small, mobile insects moving quickly across the scalp.

Transmission occurs primarily through direct head‑to‑head contact; sharing combs, hats, or bedding can also spread the parasites. Understanding these aspects is essential for effective removal strategies performed at home.

Life Cycle of Lice

The life cycle of head‑lice consists of three distinct stages that determine the timing of effective home treatment.

Eggs, commonly called nits, are attached firmly to hair shafts near the scalp. Each egg measures about 0.8 mm and requires approximately 7–10 days to hatch under optimal temperature and humidity conditions.

Nymphs emerge from the eggs and immediately begin feeding on blood. They undergo three molts, each lasting roughly 2–3 days, during which they grow in size and develop functional wings.

Adult lice appear after the final molt, reaching a length of 2–4 mm. Adults survive for about 30 days, feeding several times daily and laying up to 8 eggs per day.

Understanding these intervals informs the schedule for repeated combing and topical applications, ensuring that newly hatched nymphs are eliminated before they mature and reproduce.

Symptoms of Infestation

Lice infestation presents a distinct set of clinical signs that alert to the need for immediate action. The primary complaint is intense pruritus, especially behind the ears and at the nape of the neck. The sensation arises from the bite of the parasite and can intensify several hours after exposure.

Visible evidence includes:

Live insects, typically 2–4 mm in length, moving rapidly on the scalp.
Nits adhered firmly to hair shafts, positioned within a quarter‑inch from the scalp; they appear as oval, white or yellowish structures.
Small red or pink papules on the scalp, indicating localized inflammation.
Secondary infection signs, such as pustules or crusted lesions, resulting from scratching.

Additional indicators comprise a tickling feeling on the scalp and occasional discomfort when combing or brushing the hair. Early detection of these symptoms facilitates prompt, at‑home treatment and prevents further spread.

Preparing for Treatment

Gathering Necessary Supplies

Fine-toothed comb

The fine‑toothed comb serves as the primary mechanical method for eliminating lice and nits from the scalp. Its closely spaced teeth, typically 0.2–0.3 mm apart, allow the removal of live insects and attached eggs without damaging hair shafts.

Effective use requires the following steps:

Apply a generous amount of conditioner to damp hair; conditioner reduces slip and facilitates comb passage.
Section the hair into manageable portions using clips or hair ties.
Starting at the scalp, draw the comb through each section from root to tip in a slow, steady motion.
After each pass, wipe the teeth on a paper towel or rinse under running water to discard collected lice and nits.
Repeat the process on all sections, ensuring no area is overlooked.

Post‑treatment care includes thorough cleaning of the comb. Submerge the device in hot, soapy water for several minutes, then rinse and air‑dry. For metal combs, a brief soak in a solution of 70 % isopropyl alcohol provides additional disinfection.

Regular repetition enhances success. Perform the combing procedure every 2–3 days for at least two weeks, as newly hatched lice may emerge after the initial removal. Combining the comb with a suitable lice‑removing shampoo can further improve outcomes.

Lice shampoo or treatment

Lice shampoo or treatment provides a chemical solution that eliminates head‑lice infestations without professional assistance.

Key active ingredients include:

permethrin (1 % concentration) – neurotoxic to lice, sparing human skin;
pyrethrin (combined with piperonyl‑butoxide) – enhances penetration;
malathion (0.5 %) – organophosphate effective against resistant strains;
dimethicone (4 %) – physical coating that suffocates insects, suitable for young children.

Application procedure:

Wash hair with regular shampoo, towel‑dry.
Apply prescribed amount of lice shampoo, ensuring coverage from scalp to hair tips.
Leave product on scalp for the time specified on the label (typically 10 – 15 minutes).
Rinse thoroughly with warm water.
Comb hair with a fine‑toothed nit comb to remove dead lice and nits.
Repeat treatment after 7 days to address newly hatched lice.

Safety guidelines:

Verify age limits; products containing permethrin or pyrethrin are generally approved for children ≥ 2 months, while malathion requires ≥ 6 years.
Conduct a patch test on a small skin area 15 minutes before full application to detect hypersensitivity.
Use in a well‑ventilated space; avoid inhalation of aerosols.

Post‑treatment actions:

Wash bedding, towels, and clothing in hot water (≥ 60 °C) and dry on high heat.
Store combs and brushes in sealed containers for 24 hours before cleaning.
Maintain a weekly nit‑checking routine for 3 weeks to confirm eradication.

Towels and old clothes

Towels and previously worn garments serve as primary vectors for transferring lice and nits after a head‑infestation. Proper treatment of these textiles prevents re‑infestation and eliminates residual eggs.

Before laundering, separate items that have contacted the scalp from those that have not. Place contaminated towels, pillowcases, and worn clothing in a sealed plastic bag for at least 48 hours; this duration exceeds the survival period of lice off the host.

Laundering protocol

Wash sealed items in hot water (≥ 60 °C) with a standard detergent.
Follow with a high‑temperature dryer cycle (≥ 70 °C) for a minimum of 20 minutes.
If hot water or dryer heat is unavailable, soak fabrics in a solution of 0.5 % permethrin for 30 minutes, then rinse thoroughly and air‑dry in direct sunlight for several hours.

After washing, inspect fabrics for remaining nits using a fine‑toothed comb. Discard any items that cannot be effectively cleaned; place them in a sealed bag and store for two weeks before disposal.

Regularly replace towels and change clothing after each treatment session. Maintaining a rotation of clean textiles reduces the likelihood of accidental re‑exposure.

Preparing the Environment

Creating a controlled environment minimizes reinfestation risk and supports effective treatment.

Remove all loose clothing, hats, scarves, and accessories from the immediate area.
Place items that cannot be washed in sealed plastic bags for later processing.
Wash bedding, pillowcases, and towels in hot water (minimum 60 °C) and dry on high heat for at least 30 minutes.
Vacuum carpets, upholstered furniture, and floor mats thoroughly; discard vacuum bags or clean canisters immediately.

Disinfect surfaces that may have come into contact with hair or lice. Apply an EPA‑registered insecticide spray or a 10 % bleach solution to countertops, doorknobs, and bathroom fixtures; allow the recommended contact time before wiping clean.

Personal protective equipment should be worn during preparation. Disposable gloves protect hands from accidental exposure; a mask prevents inhalation of aerosolized particles.

All contaminated waste, including used gloves, disposable wipes, and sealed bags, must be placed in a closed container and disposed of in an outdoor trash receptacle to prevent accidental spread.

Identifying All Affected Individuals

Identifying every person who may harbor lice is a prerequisite for successful home‑based eradication. Overlooking a single carrier allows the infestation to recur despite thorough cleaning of the primary host.

Conduct a systematic visual examination of the scalp, focusing on the nape, behind the ears, and near the hairline. Use a fine‑toothed lice comb on wet hair; any live insects or viable nits indicate infestation.
Include all individuals who share close contact with the primary case: family members, roommates, and frequent playmates. Examine each person using the same combing technique.
Inspect personal items that remain in direct contact with the head—hats, scarves, hair accessories, pillowcases, and bedding. Presence of live lice or viable nits on these objects suggests additional carriers.
Document findings in a simple log, noting the date, individuals examined, and results. Repeat the inspection after 7‑10 days to catch newly hatched lice that may have been missed initially.

Comprehensive identification enables simultaneous treatment of all affected persons, preventing re‑infestation and reducing the overall duration of the outbreak.

Step-by-Step Treatment Process

Applying Lice Treatment

Following product instructions

When treating a lice infestation at home, strict adherence to the manufacturer’s directions guarantees safety and effectiveness. The product label provides essential data that must be followed without deviation.

Verify the product type (shampoo, lotion, or spray) and confirm suitability for the affected age group.
Measure the exact amount indicated; excessive use does not improve results and may increase toxicity.
Apply the preparation to dry hair, ensuring full coverage from scalp to tips. The label specifies the required contact time; maintain this interval precisely.
Rinse thoroughly if instructed, then use a fine‑toothed comb to remove live lice and nits.
Perform the recommended second application after the specified interval, typically seven to ten days, to eliminate newly hatched insects.
Store the product in a cool, dry place out of reach of children, and discard any unused portion after the expiration date.

Following these steps eliminates guesswork, reduces the risk of resistance, and supports consistent eradication of the infestation.

Important safety precautions

When treating a lice infestation at home, safety must precede effectiveness. Protective measures reduce the risk of chemical exposure, skin irritation, and accidental ingestion.

Wear disposable gloves to prevent direct contact with insecticidal solutions.
Apply treatments in a well‑ventilated area; open windows or use a fan to disperse fumes.
Keep all products out of reach of children and pets; store them in locked cabinets.
Follow the manufacturer’s dosage instructions precisely; avoid exceeding recommended concentrations.
Use a fine‑toothed comb only after the prescribed waiting period; rinse the comb with hot, soapy water after each pass.
Conduct a patch test on a small skin area 15 minutes before full application; discontinue use if redness or swelling occurs.
Dispose of used towels, bedding, and clothing in sealed bags; wash them in hot water (≥ 60 °C) and dry on high heat.

Adhering to these precautions safeguards health while ensuring the lice‑removal process remains effective.

Combing Out Lice and Nits

Sectioning the hair

Sectioning the hair creates manageable zones, allowing thorough inspection and removal of lice and nits. Divide the scalp into quadrants: front left, front right, back left, back right. Secure each quadrant with a clean hair clip before treatment.

Use a fine‑tooth comb to part hair from the scalp, pulling the strand straight away from the head.
Create sections 1–2 cm wide; narrower sections improve visibility of eggs attached to hair shafts.
Clip each section firmly to prevent overlap, ensuring the comb reaches the root without obstruction.
Process one section at a time, moving systematically from the crown to the hairline.

After completing a section, release the clip, examine the combed hair for remaining nits, and re‑section if necessary. Repeating the process across all quadrants maximizes removal efficiency and reduces the likelihood of missed infestations.

Proper combing technique

Proper combing technique is the most reliable method for eliminating head‑lice infestations without professional assistance.

Preparation

Select a fine‑toothed nit comb made of metal or sturdy plastic.
Apply a generous amount of conditioner or a specially formulated lice‑removal lotion to damp hair; this immobilises nits and eases slide of the comb.
Section the hair into 1‑inch strips using hair clips, ensuring each section is fully saturated.

Combing procedure

Starting at the scalp, draw the comb gently forward through the hair shaft to the tip.
After each pass, wipe the comb on a white tissue to expose captured lice or nits; discard visible insects promptly.
Repeat the motion 5–7 times per section before moving to the next, maintaining consistent tension on the conditioner.
Re‑apply conditioner to any dry areas discovered during the process.

Post‑treatment actions

Rinse hair thoroughly with warm water to remove residual product.
Launder clothing, bedding, and hair accessories in hot water (minimum 60 °C) or place them in a sealed bag for two weeks.
Repeat the combing routine every 2–3 days for two weeks to capture newly hatched lice before they mature.

Adhering strictly to this systematic combing protocol maximises removal efficiency and minimizes the risk of reinfestation.

Cleaning the comb

Cleaning the comb is a critical step in any at‑home lice removal routine. Residual eggs and nits cling to the teeth, allowing reinfestation if not eliminated.

Soak the comb in hot water (at least 50 °C) for 10 minutes to kill live lice.
Add a few drops of liquid detergent; agitate to break down organic matter.
Rinse thoroughly under running water to remove soap residues.
Disinfect with a solution of 70 % isopropyl alcohol; immerse for 5 minutes.
Allow the comb to air‑dry on a clean surface, avoiding direct sunlight that may degrade plastic.

After cleaning, store the comb in a sealed plastic bag until the next treatment session. Periodic inspection of the teeth ensures no remaining debris. Regular maintenance after each use prevents the comb from becoming a source of re‑contamination.

Post-Treatment Care

Washing bedding and clothes

Washing bedding and clothing eliminates lice and their eggs that survive on fabric surfaces. High temperatures destroy both adult insects and nits, preventing re‑infestation.

Recommended laundering parameters:

Water temperature: at least 130 °F (54 °C) for sheets, pillowcases, blankets, towels, and undergarments.
Cycle length: standard wash cycle, followed by a high‑heat dryer setting for a minimum of 20 minutes.
Detergent: regular laundry detergent; no additional chemicals required.

Procedure:

Separate contaminated items from untreated laundry.
Place all affected fabrics in a single load to avoid cross‑contamination.
Set washing machine to the hottest permissible cycle; confirm temperature meets the 130 °F threshold.
After washing, transfer items directly to a dryer set on high heat; avoid air‑drying.
Store cleaned items in sealed bags until the drying cycle completes.

Items that cannot endure high heat—such as delicate fabrics or certain shoes—should be sealed in airtight plastic bags for two weeks, a period sufficient to kill lice without washing.

Regular laundering of household linens, especially after treatment, maintains a lice‑free environment and supports overall eradication efforts.

Vacuuming furniture

Vacuuming upholstered surfaces eliminates live lice, nits and hatched eggs that have fallen from the scalp, reducing the risk of reinfestation. A vacuum equipped with a high‑efficiency particulate air (HEPA) filter captures microscopic particles that ordinary filters release back into the environment.

Attach a narrow nozzle to reach seams, crevices and under cushions.
Operate the machine on the highest suction setting for at least 10 seconds per area.
Move the nozzle slowly to allow airflow to dislodge adhesive nits from fabric fibers.
Empty the canister or replace the bag immediately after use; seal the waste in a plastic bag before disposal.
Clean the filter according to the manufacturer’s instructions to maintain performance.

Perform the procedure on sofas, armchairs, recliners and any fabric‑covered furniture in rooms where the infested person spends time. Repeat the process every 2–3 days for two weeks, matching the life cycle of head lice. After vacuuming, wash removable cushion covers in hot water (≥ 60 °C) and dry on high heat to ensure complete eradication.

Rechecking for lice

Rechecking for lice after an at‑home removal regimen confirms the effectiveness of the treatment and prevents reinfestation. The first inspection should occur 24 hours after the initial combing session; any surviving nymphs will become visible as they mature.

Use a fine‑tooth lice comb on dry hair, starting at the scalp and working toward the ends.
Divide hair into sections no wider than one inch; examine each section systematically.
Focus on the nape, behind the ears, and the crown, where lice preferentially reside.
After each pass, rinse the comb in hot water and wipe it clean to avoid cross‑contamination.
Record the number of live lice observed; a count of zero indicates a successful removal round.

Subsequent checks should be performed on days 3, 7, and 14. Each inspection follows the same procedure, with particular attention to any newly hatched lice that may have emerged between sessions. If live lice are detected after the third inspection, repeat the combing process for three consecutive days and continue the scheduled checks.

Persistent detection of live lice after two weeks of diligent rechecking warrants professional evaluation. Medical practitioners can prescribe topical agents or recommend alternative strategies that exceed the capabilities of household methods. «No live lice after the final check confirms complete eradication».

Natural and Alternative Remedies

Essential Oils for Lice

Tea tree oil

Tea tree oil possesses insecticidal properties that can be incorporated into a home‑based lice‑removal regimen. Its active component, terpinen‑4‑ol, disrupts the nervous system of lice, leading to rapid immobilisation.

Integrating tea tree oil into a comprehensive lice‑control plan—combined with regular combing, washing of bedding, and avoidance of shared personal items—enhances the likelihood of complete eradication without resorting to prescription‑only pharmaceuticals.

Lavender oil

Lavender oil possesses insecticidal properties that make it suitable for home lice treatment. The oil interferes with the nervous system of lice, leading to immobilization and death. Its pleasant scent also reduces discomfort during application.

Effective use requires proper dilution to avoid skin irritation. A typical concentration combines 5 ml of lavender oil with 95 ml of a carrier such as coconut or olive oil. The mixture should be applied to the scalp, ensuring coverage of the hair shaft and roots. After a 30‑minute waiting period, the hair must be combed with a fine-toothed lice comb to remove dead insects and nits.

Key points for safe application:

Perform a patch test on a small skin area before full use.
Do not exceed the recommended concentration.
Repeat the treatment every 3–4 days for a total of three applications to break the lice life cycle.
Store the oil in a cool, dark place to preserve potency.

Lavender oil can be combined with other essential oils, such as tea tree or eucalyptus, to enhance efficacy. However, each additional oil must be diluted according to the same safety guidelines. Regular monitoring of the scalp after treatment confirms the success of the lice elimination process.

Anise oil

Anise oil possesses insecticidal properties that make it suitable for addressing head‑lice infestations without professional intervention. The oil’s high anethole concentration disrupts the nervous system of lice, leading to rapid immobilisation.

Application procedure:

Dilute anise essential oil with a carrier such as coconut or olive oil at a ratio of 1 part oil to 4 parts carrier.
Apply the mixture to dry hair, ensuring thorough coverage from scalp to tips.
Comb the hair with a fine‑toothed lice comb after 15 minutes, removing dead lice and nits.
Rinse with warm water, then repeat the process after 24 hours to eliminate newly hatched lice.

Precautions:

Conduct a patch test on a small skin area 30 minutes before full application to detect possible allergic reactions.
Avoid use on children under two years of age and on individuals with known sensitivity to anise or related compounds.
Store the oil in a cool, dark place to preserve potency.

When integrated into a comprehensive home‑based lice‑removal regimen, anise oil offers an effective, natural alternative to conventional chemical treatments.

Other Home Remedies

Mayonnaise or olive oil

Mayonnaise and olive oil serve as effective suffocating agents for eliminating head lice without chemical exposure. Both substances coat the insects, blocking their respiratory spiracles and facilitating removal.

Application begins with selecting a product free of additives. Mayonnaise should be plain, containing only oil, egg yolk, and vinegar. Olive oil must be extra‑virgin, cold‑pressed, and unrefined. The chosen medium is warmed to body temperature (approximately 37 °C) to improve spreadability while avoiding scalp irritation.

Apply a generous layer to dry hair, ensuring coverage from scalp to hair tips.
Massage gently for 2–3 minutes to distribute the medium evenly.
Cover hair with a plastic shower cap; leave in place for 30–45 minutes.
Comb through with a fine‑toothed lice comb, removing dead insects and nits.
Rinse hair with lukewarm water and a mild shampoo to eliminate residue.

After treatment, repeat the process after 7 days to address any newly hatched lice. Inspect hair daily for several weeks; persistent nits warrant a second application of the same method. Regular washing with standard shampoo maintains scalp hygiene and reduces reinfestation risk.

Vinegar rinses

Vinegar rinses provide an acidic environment that helps loosen the glue used by lice to attach their eggs to hair shafts. The solution is simple to prepare: mix one part white distilled vinegar with two parts lukewarm water. Apply the mixture to clean, towel‑dry hair, ensuring thorough saturation from scalp to tips. Allow the rinse to sit for five to ten minutes; the acidity softens the egg casing, facilitating removal.

After the waiting period, use a fine‑toothed nit comb to slide through the hair in sections. Begin at the scalp and pull the comb toward the ends, cleaning the comb after each pass. Repeat the combing process until no live lice or nits are visible. Rinse the hair with plain water to eliminate residual vinegar and dry with a clean towel.

Key considerations for effective use:

Perform the rinse once daily for three consecutive days, then repeat after one week to address any newly hatched lice.
Avoid applying the solution to irritated or broken skin; rinse immediately if discomfort occurs.
Do not combine vinegar rinses with strong alkaline products, as the chemical interaction may cause scalp irritation.
Store any unused mixture in a sealed container for up to 24 hours; discard after this period to prevent bacterial growth.

When integrated with regular combing and proper hygiene practices, vinegar rinses contribute to a comprehensive, at‑home strategy for eliminating head lice.

Effectiveness and Risks

Home‑based lice removal relies on chemical and mechanical approaches, each presenting distinct efficacy levels and safety considerations.

Over‑the‑counter pediculicides – contain pyrethrins or dimethicone; achieve 80‑95 % elimination of live insects after a single application; skin irritation, allergic reactions, and resistance development represent primary risks.
Hot water wash – soaking combs, hair accessories, and bedding at ≥ 60 °C for 10 minutes; eradicates all life stages on treated items; risk limited to potential fabric shrinkage or damage to heat‑sensitive materials.
Fine‑toothed nit combing – manual removal after applying a conditioner to immobilize insects; success rates range from 60‑80 % when performed daily for two weeks; risks include scalp abrasion and incomplete extraction leading to reinfestation.
Vinegar or alcohol rinses – dilute solutions intended to dissolve egg glue; modest reduction in nits (~30‑40 %); potential for scalp dryness, irritation, and limited penetration to deeper hair layers.
Essential‑oil mixtures – formulations with tea tree, lavender, or peppermint oil; anecdotal reports suggest 40‑60 % reduction in adult lice; risks encompass allergic dermatitis and variability in product quality.

Effectiveness correlates directly with thoroughness of application and adherence to repeat‑treatment schedules. Risks intensify when products are used beyond manufacturer‑recommended concentrations or applied to vulnerable populations such as infants and individuals with pre‑existing skin conditions. Selecting a method requires balancing eradication potential against the probability of adverse skin or material reactions.

Preventing Reinfestation

Regular Head Checks

Regular head examinations are a cornerstone of effective lice management. Detecting nymphs and adult insects early prevents extensive infestation and reduces the need for aggressive treatments.

Key practices for systematic checks:

Perform examinations every 2–3 days during the active phase of treatment and for at least two weeks afterward.
Use a fine-tooth comb on damp, conditioned hair to capture lice and eggs.
Divide hair into sections, starting at the scalp and moving outward, to ensure thorough coverage.
Inspect the comb after each pass; remove captured specimens with a disposable tissue.
Record findings in a simple log, noting the number of live insects and nits observed.

Optimal conditions for examinations include natural light or a bright lamp, a clean, flat surface, and a calm environment to keep the child still. If any live lice are found, repeat the combing process immediately and continue the routine until no insects appear for three consecutive checks.

Educating Children

Educating children about safe removal of head lice empowers them to participate actively in personal hygiene and reduces reliance on external assistance. Clear, age‑appropriate instruction eliminates confusion and promotes consistent practice.

Key steps for effective home treatment:

Identify infestation by inspecting scalp and hair shafts for live insects and nits.
Apply a medically approved lice‑removing product according to label directions; avoid excessive quantities.
Use a fine‑toothed comb on damp hair, moving from scalp outward in systematic sections.
Rinse comb frequently with hot water to prevent re‑attachment.
Repeat combing after 24 hours and again after seven days to capture newly hatched lice.
Wash clothing, bedding, and personal items in hot water (≥ 60 °C) or seal them in plastic bags for two weeks.

Communication techniques reinforce learning:

Demonstrate each step in a calm, step‑by‑step manner, allowing the child to observe before attempting.
Encourage questions and provide concise answers without exaggeration.
Use visual aids, such as illustrated guides, to illustrate combing technique and product application.

Preventive education completes the cycle:

Teach regular self‑inspection, especially after group activities.
Emphasize avoiding head‑to‑head contact and sharing personal items such as hats or brushes.
Reinforce routine hair washing and proper storage of personal belongings.

Consistent instruction, practical demonstration, and ongoing reinforcement create a self‑sufficient approach to managing lice infestations within the household.

Avoiding Sharing Personal Items

Avoiding the exchange of personal items is essential for preventing the spread of lice during home treatment. Sharing objects that contact hair or scalp creates a direct route for eggs and nymphs to move between individuals, undermining any cleaning efforts.

Key items that should never be shared include:

combs and brushes
hats, caps, and headbands
hair clips, pins, and elastics
pillows and pillowcases
towels and washcloths
headphones and earbuds
scarves and bandanas

Practical measures reinforce this precaution. Label all grooming tools with a name or initials, store them in a sealed container when not in use, and keep them separate from communal supplies. If an item must be used by more than one person, wash it in hot water (minimum 130 °F) and dry on high heat before each use. Disinfect hard surfaces such as hair‑dryers and styling equipment with an appropriate lice‑killing solution. By consistently isolating «personal items», the risk of re‑infestation diminishes, supporting effective lice removal at home.

Maintaining Cleanliness

Maintaining strict cleanliness is essential when addressing head‑lice infestations at home. Effective elimination depends on removing viable insects and preventing re‑infestation through thorough hygiene practices.

Wash all bedding, clothing, and towels in hot water (minimum 130 °F) and dry on high heat.
Soak combs, brushes, and hair accessories in a solution of 1 part vinegar to 3 parts water for at least 30 minutes, then rinse and air‑dry.
Vacuum carpets, upholstered furniture, and floor surfaces to capture stray lice and nits.
Seal non‑washable items (e.g., stuffed toys) in airtight bags for two weeks to starve remaining parasites.

Regular cleaning schedules reinforce treatment outcomes. Replace pillowcases and sheets weekly until no lice are detected. Disinfect hair‑care tools after each use with an alcohol‑based solution. Keep personal items separate; avoid sharing hats, scarves, or hair accessories. Consistent application of these measures reduces the risk of recurrence and supports a lice‑free environment.
