One last point, you actually don't need to go overboard on washing all the clothing etc. Lice are transferred through head to head contact, they will not voluntarily leave the hair. Any that do come off are dying anyway.

I spent a lot of time researching this, including reading medical papers when my daughter first came home with lice!
Hair type: 2c-M-ii with extra frizz
