Some men have areas on the scalp that are very sensitive to the male sex hormones that circulate in men's blood. The hormones make the hair follicles - from which hair grows - shrink. Eventually, they become so small that they cannot replace lost hairs. The follicles are still alive, but are no longer able to perform their task. The condition usually starts in men aged 20 to 30 and follows a typical pattern. First, a receding hairline develops, and gradually the hair on top of the head also begins to thin. Eventually, the two balding areas meet to form a typical U-shape around the back and sides of the head. The hair that remains is often finer, and does not grow as quickly as it used to.

Do lost hairs come back? Yes, they come back

The rationale to prevent hair loss in man or women in case of androgenetic alopecia is to block the 5 alpha reductase enzyme activity on the scalp and interrupt the interaction of DHT with the hair follicle. Nowadays there are many natural compounds with the proven anti-hair loss activity. The most well-known ones are sereno repens (saw palmetto), green tea (Camellia sinensis) extract (EGCG), grape seed extract, beta-sitosterol, ginseng extract, and apple procyanidins. They either block the activity of 5 alpha reductase enzymes or the binding of DHT to receptors in the hair follicle or block both activities. There are also some chemical compounds that block the activity of 5 alpha reductase enzyme activity, but exert serious side effects or have limitations to use. Also there is no known chemical compound that blocks both the activity of 5 alpha reductase enzymes and the binding of DHT to receptors in the hair follicle.

Revigen tablets have green tea extract, Panax ginseng root extract, grape seed extract, soya isoflavone daidzein extract, folic acid and zinc. Revigen tablets help nourish hair follicle that leads to get your hair back as healthy as before. Green tea extract prevents hair follicle from internal and external damages. Soy isoflavone daidzein is another powerful extract that keeps hair follicle alive. Grape seed extract is a powerful anti-oxidant that leads to promote hair re-growth as it stimulates hair follicle. The compounds in Panax ginseng root extract activate hair growth. It also has anti-stress properties in that it effectively stops hair loss due to ordinary stress. Hair follicle cells need zinc and folic acid to regenerate.
