Treat contacts if they have active lice infestation.
1. Insecticides – Malathion 0.5% or Permethrin 5%
2. Wet combing – Bug buster kit. Requires a minimum of four sessions spaced over two weeks and should be continued until absence of full grown lice is seen for three consecutive sessions.
3. Dimeticone 4% (Hedrin) – dimeticone lotion applied to dry hair and scalp should be kept on for 8 hours or overnight and repeat after 7 days.
In a pregnant or lactating woman wet combing or dimeticone is advised.
