Hairgenx HAIR GROWTH COMPLEX FOR HER. A natural Hair Loss Supplement and powerful DHT Blocker, formulated from a proprietary blend of natural herbal extracts that have been scientifically proven to combat thinning hair and hair loss by inhibiting the production of the 5-A Reductase enzyme in the body, which prevents the formation of the more potent and destructive androgen Dihydrotestosterone (DHT). For those who are so predisposed, this androgen attaches to follicle receptors cutting of blood flow preventing the absorption of vital nutrients. This results in the hair becoming thinner and thinner until it is lost.
