This medication is used to treat head and crab (pubic) lice. Lice are tiny insects that lay eggs (nits) on hair shafts. Lice can easily spread to those in close contact with you. Lindane works by killing the lice and nits. An infection with lice is also called an infestation. This drug should not be used to prevent lice infestation or re-infestation.
Wash your hair with your regular shampoo (without conditioner) and dry it well.
Wait at least 1 hour after drying your hair before using Kwell shampoo.
