Pour KP24 medicated Lotion onto dry hair. Use enough to thoroughly cover scalp, massage well into the scalp to provide good contact with any lice eggs. You should not need more than 25ml for shoulder length hair. Allow to dry naturally, do not heat. If you leave the lotion on for 8-12 hours it will provide you with a preventative effect from reinfestation. Remove all the eggs(nits) you can find after treatment . Use KP24 fine tooth metal lice comb to remove eggs.
As a precautionary measure repeat treatment after 7 days to kill lice that have hatched since.
