I am sick and tired of head lice infestations of my kids and now grand-kids; solutions please?

Head lice. Tx of lice requires accurate identification of nits & lice. A pediculicide is usually used- OTC like Nix 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.
Head Lice. The article from the cdc is helpful. http://www.cdc.gov/parasites/lice/head/gen_info/faqs.html.
Okay. Combing alone e it help but dose not for sure clean it up, use the recommended shampoo, for the whole family, clean all the bed sheets sand if you have bets also do it for them.
