I am 50+, and have overplucked my eyebrows to the point of "no return"... Until now... this stuff really WORKS! You must be diligent and patient; but with continued used, as directed; I now have new hair growth, the "blank" spaces are filling in, and only use a small amount of brow pencil to fill. For the 1st time in YEARS, I can go outside without painting on brows. THANK YOU.
