The Creepy Lice Cure - hopefully

My denial folded last night, I had to confront the fact that I had come home with the dreaded DR lice that  occupy heads of compound Cocoa Hollow. Paradise is happy place for parasites too. So I'm sitting here with hair coated in an olive oil/neem oil mixture (Neem is definitely an acquired smell) , head wrapped in a plastic bag, feeling as if the little buggers are trying to escape. Creepy  crawly feeling over the scalp. I want to scratch. Better not! Two hours in this cap MAY thwart the nasty ones. But I suspect I should adopt this routine for a few more days. Unsure of the best prescription - this is a test, trying to avoid the chemicals.
