MALE PATTERN BALDNESS
Androgenetic alopecia (AGA), also known as male pattern baldness, is one of the most common conditions affecting men. In the United States alone there are over 35 million men are affected by AGA.
Recession of the temporal area is typically the first place of hair loss; in some men the loss stops there and never progresses while in others it can continue into other areas of the scalp. Progression can vary being rapid in some men and slower in others.
No matter how severe the hair loss, hair is not lost at the back or sides of the head. These regions are genetically different from hair follicles found in the front and top of the head. The hair at the back and sides of the head can be harvested and transplanted to bald or thinning areas and continue to grow as they would on the side and back of the head.
