i've heard of that too cure, but just by word of mouth
i'm just reading up on it...

Testosterone, a hormone that is present in high levels in males after puberty, is converted to dihydrotestosterone (DHT) by an enzyme called 5-alpha reductase. DHT has an adverse affect on the hair follicles. Acting on a hormone receptor on the hair follicle it slows down hair production and produces weak, shorter hair, sometimes it stops hair growth from the follicle completely. This process gradually depletes your stock of hair and is normal hair loss.

Studies show that zinc may protect hair follicles from excess DHT, the main factor in androgenic (male) pattern hair loss. Zinc is often associated with hair regrowth and used to help prevent and treat hair loss. Zinc has been shown to be a potent inhibitor of 5 alpha-reductase activity. Vitamin B6, along with zinc improves this activity.
anything to support that zinc inhibitor claim?

Cations Inhibit Specifically Type I 5alpha-Reductase Found in Human Skin
Steroid 5alpha-reductase catalyzes the reduction of testosterone into the very potent androgen dihydrotestosterone. Previously, we showed that human type I 5alpha-reductase is expressed mainly in the skin, whereas a type II 5alpha-reductase is more specifically expressed in tile prostate. To assess the possible differential effects of various cations on the two types of 5alpha- reductase, we constructed expression vectors and transfected them into SW-13 cells, a human adrenal carcinoma cell line containing negligible endogenous 5alpha-reductase activity. The expressed 5alpha-reductases were analyzed for their sensitivity to Li, Ca, Cd, Cu, Mg, Mn, Ni, Zn, and Fe. The results showed that type I 5alpha-reductase was strongly inhibited by Cd, Cu, and Zn and moderately inhibited by Ni and Fe, with 50% inhibitory concentration values of 0.9, 1.9, 2.0, 169,2, and 174.3 muM, respectively. In contrast, type II 5a-reductase activity was inhibited only by Cu, with a 50% inhibitory concentration value of 19.2 muM. The data showed that cations could specifically control 5alpha-reductase activity expression, which is more strongly inhibited in a target tissue, especially the skin.
