Medical hair restoration in the literal sense includes the hair loss treatment which depends on the use of drugs.

Unusual hair loss in men and women is caused by changes in the metabolism of androgens. Androgen is a male hormone, which plays an important role in the regulation of hair growth or hair loss. The dermal papilla is the most important structure in a hair follicle responsible for hair growth. This is the dermal papilla, the cell divides and differentiates to rise to give a new hair follicles. The dermal papilla is to move into direct contact with capillaries in the skin of the nutrients for the growth of hair follicles. Research has shown that dermal papilla has many receptors for androgens and there are studies confirming that men have more androgen receptors in dermal papilla of their follicles as compared to females.

The metabolism of androgen involves an enzyme called 5-alpha reductase which combines with the hormone (testosterone) to the androgen DHT form (dihydro-testosterone). DHT is a natural metabolite of our body that is causing hair loss.

Good nutrition is essential for the maintenance of hair. When DHT in the hair follicles and hair roots (dermal papilla) prevents proteins, vitamins and minerals to foods that are for life in the hair of these follicles. Consequently, the hair follicles are reproduced at a much slower pace. This shortens the prolonged growth phase (anagen phase) and or their resting phase (telogen) of the follicle. DHT causes hair follicles to shrink and even smaller and finer. This process is known as miniaturization and causes the hair eventually fall. DHT is responsible for 95% of hair loss.
Some people, men and women are genetically predisposed to produce more DHT than the normal individuals. DHT also creates a wax-like substance in the hair roots. It is this accumulation of DHT in the hair follicles and roots, which is one of the major causes of hair loss in men and women. » Read more: Medical Hair Restoration
