i know i'm the first to reply to most things, but i swear i'm not trying to hog the forum. :)
Renee, that treatment looked sketchy to me, but it doesn't mean that it is.
the thing i don't really like is the huge amount of rubbing alcohol thats in the recipe. although it may not damage hair follicles in small amounts, it definitely can be a serious scalp irritant. cause redness, itchiness, flakes.. etc. i just read something that a doctor wrote and he said approximately 10% of people have a reaction like this to alcohol when applied topically. that stuff scares me, so i'm most certainly biased.
don't forget that hair is a sign of health for many and most, so if yours is just thinning you may even be able to just take vitamin or herbal supplements or both.
