My husband uses the Men Serum with a good results, and I've recently shown signs of thinning, scary, so have now been using the Womens version (not sure of the exact differences, they smell very similar), for several weeks, and there genuinely does seem to have been an improvement. Maybe I'll report back after 3 month, if anyone is interested. Also taken a 'Before' image, so can show if there has definitely been an improvement. I'll give Reseed 5 Stars, because of the combination of my husbands success and my fingers being literally crossed for my trial. Thanks x
