NItty Gritty Solution uses safe, proven natural ingredients instead of nasty chemical pesticides. After all, why put something on your children that you probably wouldn&39t use on your garden? We three mums tried every chemical pesticide on the market when our own daughters were going through &39head lice hell&39 in their teens. We found that there wasn&39t one single safe, effective head lice treatment available anywhere, & many of the products we tried were far more harmful to our children than head lice. We realised there had to be a better way... & this is it. Made by mums, kind to kids, & it really works, which is why our Solution unlike anyone else&39s, comes with our lifetime money-back guarantee of effectiveness. Used in conjunction with our Nitty Gritty Nit Free Comb it gives unbeatable results. Helps the comb to glide smoothly & effortlessly through any hair type. Unlike some regular hair conditioner, our Solution won&39t foam up when you use it, so you can really see what you&39re getting out. YUK! Note: When purchased separately from the Nitty Gritty Comb, the Solution is supplied with a regular white plastic nit comb.
