Use tea tree oil with lavender oil or coconut oil to treat lice. Anti-lice shampoos and other chemical treatments can be harsh, especially on children. A natural, safe alternative is tea tree oil, used alone or in combination with gentle treatments like nerolidol, lavender oil, or coconut oil. It can be used as a spray or added to a shampoo. To use: massage the sol. onto the scalp and hair; wash off and comb wet hair to remove the dead lice.
