Head lice have been around for thousands of years, and will most likely be around for thousands more. However, there are a variety of treatments for lice. So even though you can’t “cure” lice, you can be lice-free if you kill or remove all the lice and lice nits on your head (and assuming you don’t get infested again).
Lice treatment products come in a variety of forms, including sprays, gels, shampoos, topical drugs, combs and medical devices. Most of these are available for home lice treatment, but some are available only at a professional lice business.
