Hi Lady,..I am also wondering the same question...I am 35 and very thin on my crown but I live in Canada and they don't sell it here for women yet, just for men. I hope some women out there answer this post with any tips or suggestions because I'm sure there are more women with thinning hair these days than years ago... Right now I use a hair concealer to color my scalp to reduce the contrast between my hair and my scalp and it works pretty good but I would like to stop any more from thinning! Good Luck!!
