How do you get rid of the actual nits (ie headlice eggs)?

[Buckets]

Am pretty sure there are no live ones left (have been washing with teatree shampoo once a week and combing with conditioner twice a week for the last month) but there are still loads of eggs stuck on. My metal comb is ok for lice but doesn't shift the eggs - is there a different comb you need for that or do you have to strip them off individually with fingernails? Or do they just drop off eventually?

nitty gritty? you just have wait until they hatch [grim] then get them with comb

you need to wet comb every nigth for a week

second nitty gritty comb

yes you must get one if you dont have already

they are a thing of miracles

Okedoke, sounds like a good investment, where can I buy one?
Thanks
