This stuff worked very well for making the 27 hairs on my head look like 42. Well, that's a slight exaggeration, but only slight. Thyroid meds have thinned my hair alarmingly and the problem is not going to improve. I have those deep, inverted "V's" at the sides of my forehead and have to work hard at a partial comb-over to cover them, so when I read about this product, I was excited. I have baby fine, thin hair that has always been a problem ..
