Hi,
Thanks for posting in HCM.
I have read your description and understand your concern.
Head lice can be difficult to treat due to the time-consuming, precise nature of treatment and high re-infestation rate.
The following things can be done to overcome the problem:
1. Wet combing - It is a method that involves removing the head lice by systematically combing the hair using a special fine-toothed comb.
2. Lotion or sprays - A lotion or spray should only be used if a living (moving) head louse is found.
3. Washing clothing: The most common way to kill body lice and eggs is to wash clothing and bedding in hot water [130°F (54.5°C) or higher].
4. Permethrin creme rinse 1% which is a common first choice for treating head lice.
If it does not respond to above measures, you need to go for:
1. Benzyl alcohol 5%, which is applied to the hair on the head, left on for 10 minutes, and then rinsed off.
or
2. Malathion lotion which is applied to hair on the head, left on for 8 to 12 hours, then rinsed off. If lice are still present 7 to 9 days later, a second treatment must be done.
Hope the information provided would be helpful.
All the best.
