Could you tell me what gets rid of lice for good?

How2get rid of lice: Lice have developed resistance to some of the medicines currently available, in my practice applying petroleum jelly to hair and sleeping over night with it in the hair kills the lice and loosens the nits. Good combing after this helps.

Lice tx: Tx of lice requires accurate identification of nits & / or lice. A pediculicide is usually used- otc like nix (permethrin) or rid or prescription meds like lindane or malathion. Work carefully through hair & remove individual nits. Purchase a special lice nit comb to aid you. Check for nits & remove as seen over the next 7 to 10 days. If there are nits after 7 to 10 days – a 2nd pediculicide tx may be needed.
