I had lice soo many times when I was young

Fried Lice Moose works well and so does KP24 ,Conditioner and a lice comb which you can get from the chemist and comb the eggs out that way.. The Fried lice and KP24 in pink will kill the live lice but won't kill the eggs you will need to comb them out yourself.. Also put all your sheets etc in the wash but first soak with hot water and disinfectant because you will find you will keep getting them ... And remember that they jump onto clean hair so don't think LO is dirty ok

When sending LO to daycare or wherever get some lavender oil in water spray onto the hair and it will deter the headlice... I am a hairdresser know how to tackle these things straight away
KP24 (and a couple of other brands) burnt the hec out of my head when I was young. Not saying that'll happen to your LO's but just so you know it can happen.

Lice don't discriminate, clean/ dirty/ long/ short hair.
They dont jump (lots of people think they do though), they need direct contact ie, touching heads/ a way to crawl onto the next head
I have heard of the Lavender thing but never tried it. We used to use a few drops of tea tree oil in a spray bottle, and spray the hair once or twice a week, which worked great to keep them away.

We never did find a treatment that worked really well But the lice treatments with tea tree oil worked best.

It's so horrible, I hope you can get rid of them quickly. *shivers* Just thinking about it is giving me the heeby jeebies.
