When it comes to eliminating a lice infestation, it's all about the comb. The WelComb is the most effective lice and nit removal comb. The WelComb is NEW and unlike any other lice comb on the market. There is NO pesticide or natural solution that can harm or kill nits (lice eggs). The only way to ensure nits won't hatch and continue to spread is to physically remove them with a WelComb!
