My acupuncturist told me about it when i went in for treatment for hormone problems and inflammation on the scalp (and hair thinning). its helped me a lot, but i use it in conjunction with acupuncture treatment.
I found the soap when doing a google search for hair thickening products. found them and never looked back. but ive learnt a lot about hair care thanks to them, and just because of that i have some sexy hair growth coming on all the time.
