Male Pattern baldness is a hair loss problem that affects more than 70 percent of all men over the age range of 16-50 to some extent.  It usually depends on genetics or having a family history of baldness and if necessary actions are not performed, it may lead to irreversible baldness. Research has found that male pattern baldness is associated with male sex hormones called androgens.

Male Pattern Baldness does not occur overnight. In fact, it a process generally starts at the early age of 16 to 20 and continue until the age of 50. The first sign is decrease of hair growth. It is then followed by having dull, thin hair that is prone to breakage. Male pattern baldness is characterized by receding hairline from the side and top of the temple. This leads to gradual development of a bald patch in the center of the scalp (at the crown of the head). The receding lines slowly tend to spread and merge with the bald patch. A patchy baldness is the final outcome of male pattern baldness (which might lead to complete baldness if not controlled).
