- loosen the nits with either plain white vinegar or an "egg releaser" product such as Clear. Both Clear and vinegar work well but might neutralize the active ingredient in the Nix ( permethrin) and therefore should be used before the Nix and rinsed out thoroughly.
- Wash hair with Prell Shampoo. Other shampoos with a silicon or lipid based conditioner might coat the lice and eggs and protect them from the Nix
- Towel dry the hair so that it is still damp. Work the Nix through the hair and leave on for 30 minutes. ( ignore the package insert that says 10 minutes)
- Rinse out the Nix and comb out the lice and nits. ( this is usually when you will see dead lice)
- Getting a special Lice Comb will make this job much easier. Metal flea combs from the pet store work, but the best one is probably the Lice Meister comb. (You can find it on Amazon for about $18.) The plastic one that comes with the Nix is pretty worthless.
As of June 2013 you can go to www.SKLICE.COM for a $25 copay coupon.
This website will give you all the directions that you need along with other useful lice info.
Update 11/14 There has been a back order on Sklice and we have had a hard time finding it in the SF Bay Area.
I will update when it is widely available again.
