About Hair Loss In Men

The most common type of hair loss in men is called androgenic alopecia. This is hair loss that is hereditary and results in increased sensitivity of hair follicles in certain regions of the scalp to male sex hormones.

In predisposed individuals, DHT (dihydrotestosterone), which is an androgen (male sex hormone) circulates in the scalp and causes predisposed hair follicles to shrink and eventually they fall out, never to be replaced.

The condition of male pattern hair loss usually starts in men in their 20’s and 30’s and follows a pattern that can involve only the frontal scalp, the crown, or the frontal scalp, mid scalp and crown. Usually the back and sides of the scalp are spared any hair loss, as this hair type is resistant to androgenic alopecia. Thus when hair from the back and sides of the scalp are moved to any other part of the scalp, they can go on to grow forever and not be affected by the hormonal factors that cause male pattern hair loss.
