The most universal reason of male pattern baldness is genetics. Genetics makes the individual pre-disposed to androgenetic hair loss or pattern baldness by determining both the density and the location of androgen-sensitive hair follicles. Apart from genetic or hereditary issues hormonal factors, especially androgens, play an important role in pattern baldness. Some common reasons of hair loss in both genders are improper diet, smoking, stress, hormonal imbalance, DHEA supplements, etc.
