How to treat lice in long hair? - in detail
Treating head lice in long hair requires careful preparation, thorough application of treatment, and diligent follow‑up.
Begin by separating the hair into manageable sections. Use a fine‑toothed lice comb on dry hair to remove adult insects and nits before any chemical product is applied. Work from the scalp outward, combing each section several times to dislodge as many organisms as possible.
Select an appropriate pediculicide. Options include:
- Permethrin‑based lotions applied to the scalp and hair for ten minutes, then rinsed thoroughly.
- Dimethicone‑based sprays that coat lice and prevent respiration, leaving the product on the hair for at least thirty minutes.
- Non‑chemical treatments such as heated air devices that raise hair temperature to lethal levels for lice, applied according to manufacturer instructions.
Apply the chosen product uniformly, ensuring coverage from the roots to the tips. For long hair, the following steps improve penetration:
- Damp the hair with lukewarm water to facilitate even distribution.
- Dispense the treatment onto the scalp, then massage gently toward the ends.
- Use a wide‑tooth comb to spread the product through each section, maintaining contact for the recommended exposure time.
After the exposure period, rinse hair with warm water and shampoo as directed. Repeat the combing process with a fresh lice comb to capture any surviving nits.
Schedule a second treatment according to product guidelines, typically seven to ten days after the first application. This interval targets newly hatched lice before they mature.
Maintain a clean environment to prevent re‑infestation:
- Wash bedding, clothing, and towels in hot water (≥ 60 °C) and dry on high heat.
- Vacuum carpets, upholstered furniture, and vehicle seats.
- Seal non‑washable items in sealed plastic bags for two weeks.
Monitor the scalp for three weeks, performing weekly comb checks. Absence of live lice and nits confirms successful eradication.
If symptoms persist after two treatment cycles, consult a healthcare professional for alternative therapies or prescription‑strength options.
