What happens in male pattern baldness?

MPB is an inherited condition, where hair follicles in the affected regions of the scalp have a genetically determined sensitivity to the effects of a male hormone derivative or by-product called dihydrotestosterone (DHT). DHT is believed to shorten the growth phase of the hair cycle, causes the follicle to shrink (miniaturization) and produce progressively fewer and finer hairs. The production of the DHT hormone is controlled by an enzyme called 5-alpha reductase.

Typically the hair follicles in the frontal through mid-scalp to the crown can be genetically sensitive to the effects of DHT, whilst most hair follicles at the back and sides of the scalp are resistant to such effects of DHT, therefore remain permanent even with extensive male pattern hair loss. This DHT resistance continues even when these hair follicles are transplanted into the areas of hair loss and enables the results of hair transplant to be long lasting.
