How can the scalp be treated after lice? - in detail
After eliminating the parasites, the scalp requires a systematic approach to restore comfort and prevent secondary problems. Begin with thorough rinsing using lukewarm water and a mild, sulfate‑free shampoo. This removes residual chemicals from lice treatments and any dead insects. Follow the wash with a gentle massage to stimulate circulation and dislodge remaining debris.
For irritation relief, apply a soothing lotion containing aloe vera, calendula, or chamomile extract. These ingredients calm inflammation without introducing allergens. In cases of pronounced itching, a low‑potency hydrocortisone cream (1 %) may be used for up to three days, followed by a non‑steroidal anti‑itch option such as a menthol or pramoxine gel.
Moisture balance is crucial. After cleansing, pat the skin dry and apply a lightweight, fragrance‑free emollient—e.g., a ceramide‑based moisturizer or a natural oil like jojoba. This restores the protective lipid layer and reduces dryness caused by frequent washing.
If the scalp appears scaly or flaky, incorporate a weekly treatment with a 1 % salicylic acid scalp serum. Apply a thin layer, leave for five minutes, then rinse thoroughly. This helps exfoliate dead cells and prevents buildup.
Avoid the following during the recovery period:
- Hair products containing alcohol, strong fragrances, or harsh preservatives.
- Heat styling tools that can worsen irritation.
- Tight hairstyles that increase tension on the scalp.
Maintain a clean environment by washing bedding, towels, and clothing in hot water (≥ 60 °C) and vacuuming upholstery. Regularly disinfect combs and brushes with a solution of 70 % isopropyl alcohol.
Monitor the scalp for signs of infection—persistent redness, swelling, pus, or fever. If any of these appear, seek medical evaluation promptly.
