Picture of Male Pattern Baldness
Male pattern baldness accounts for the vast majority, more than 95%, of hair loss in men. It is a form of androgenetic alopeceia. Approximately two-thirds of men in the U.S. will have substantial hair loss by the age of 35. By age 50, an estimated 85% of men will have thinning hair. About 25% of men will begin to lose their hair before the age of 21. Hair loss can be psychologically detrimental for men and may encumber their professional lives and interpersonal relationships.
