Steps for treating head lice with 4% dimethicone lotion
To use 4% dimethicone lotion, take the following steps.
Put the lotion on to dry hair. Work it in around the head and cover the hair with the lotion right to the ends - use enough lotion to completely moisten the hair and scalp.
Comb the hair with an ordinary comb to make sure the lotion covers all the hair evenly.
Leave the lotion to dry naturally. There's no need to cover the hair with a wrap. Head lice can't move within a minute of being covered with 4% dimethicone lotion.
Wait at least 8 hours before washing the hair with your normal shampoo.
You can use a fine-tooth head lice comb to remove the remaining eggs after treatment and any dead lice that were not washed out - this step is not essential.
Repeat in 7 days.
