head lice
"I have had head lice for 3 months, my teen age daughter passed it to me. I have thick curly hair. I'm desperate. I have used permethrins, and other over the counter medications. It seems it tames the lice, it stops itching me for 3 or 4 days and I go back again with itching. I am not infested. It is just one two or three that keeps on surviving. Some body checks my hair about every week and she can't find eggs but I see the red bumps in my scalp. I am going to get this natroba and I am praying it will work. I can't sleep because my scalp itches."
