Hair Transplant Basics: What is Follicular Unit hair transplant?

Baldness and thinning of scalp hair are conditions that affect almost one-third of all men in their thirties and, fifty percent by their fifties.  Infrequently, some women also experience noticeable hair loss. There are many causes for temporary hair loss including systemic diseases, severe infection, anemia, thyroid disease, protein, vitamin and mineral deficiency, certain drugs, cancer treatments, childbirth and birth control pills. In this type of hair fall the root of hair is not destroyed. Therefore hair loss is temporary and corrects after the offending agent is withdrawn.

However, when hair root is destroyed, the loss of hair is permanent. The causes include direct trauma such as accidents, burns, operations and inflammatory or infectious diseases of the scalp. But, the most common type of permanent hair loss is Androgenetic alopecia, the exact cause of which is not known. However a hormonal byproduct called DHT has a significant role to play. It is postulated that people who have hair roots with increased genetic susceptibility to DHT suffer more severe hair loss. Since DHT is present in very small quantities in women, they do not generally suffer this type of hair loss.In Androgenetic alopecia, hair loss occurs typically from front and top portions of head, while sides and back hair are retained. 

Artificial coverage of bald area can be done with hairpieces and fibers, but many people find them unnatural looking or difficult to maintain. There are some medicines and oils in the market that claim to restore hair growth with limited success. Although medicines like Finasteride (Propecia) and Minoxidil (Rogaine) may stop hairfall to an extent, no amount of medicines can bring lost hair back. Follicular unit hair transplant is the only predictable, natural and permanent solution for those who are bald or have thinning hair. Hair transplants or grafting is a procedure which produces natural growing hair in bald areas.
