Dimethicone Lotion For Treating Head Lice

Dimethicone Lotion For Treating Head Lice

4% dimethicone lotion is a very effective head lice treatment that a health professional can prescribe.


Step by step 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
  • wait at least 8 hours before washing the hair with your normal shampoo
  • 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
  • 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
