A naturopath recommended this product to me, in a effort to combat a hair loss problem caused by hormonal imbalances. My testosterone is way too high and this supplement is formulated to not only reduce the testosterone, but also strengthen the hair. Just what I am aiming for! I have only been using the product for a month, but I always remember to take it, unusual for me. Better yet, I quit worrying, so something is working--and there do seem to be a flurry of new little hairs sprouting along my hairline.
