I'm a 50ish woman who has noticed thinning areas on the to of my head, this product has been wonderful for me, it covers,doesn't clump, run or even look like I'm wearing anything to disguise the area. I am so satisfied, I brought it over to my hairdresser, and she uses it on her clientele..There is one thing though, the bottom of the bottle is weighted and I'm never sure when I'm running low..wish they could address that...
