Tea tree oil mixed with conditioner works very well. We left it on for about an hour, seemed to kill all the head lice. Will be repeating it in a few days time to get rid of the newly hatched ones as there were lots of eggs!
Reply: Thanks for sharing your tip with using tea tree oil and hair conditioner. Looks like a great way to get rid of those nasty lice and soften and condition the hair at the same time. Probably a lot more easier on the hair than using a strong pesticide-formulation on the hair and scalp.
