High DHT levels result in the shrinkage of the hair on the scalp which leads to baldness. DHT is formed by the 5alpha-reductase enzyme which converts testosterone to DHT. This leads to a shortening of the growth cycle of your strands and leads to follicular miniaturisation and progressively thinner and shorter hair. New hair takes time to replace the damaged hairs in the hair follicles. Finasteride curbs the action of 5alpha-reductase preventing the conversion to DHT and thereby prevents hair loss. Topical Finasteride Topical Finasteride is advantageous for those people who are vulnerable to the side effects of oral finasteride. However, despite conflicting claims about the relative efficacy of both systems, most are in agreement about the more potent benefits of using a combination of the two.
