Black Men Male Pattern Baldness
Baldness involves loss of hair, and a lack of further growth especially on the head. It is a condition of hair thinning known as androgenic alopecia or male pattern baldness. The pattern baldness differs with population and related to genetic background. Generally environmental factors do not have any bearing on baldness.
A large scale study conducted in Australia had indicated that mid-frontal hair loss increases with age and affects 57 percent women and 80 percent men of 80 years and above. In the United States it is reported that 25 percent men begin balding at 30 years and 66 percent men do by 60 years.
One theory suggests that evolution of baldness in the male is through sexual selection and signaling of ageing and social maturity to reduce risk taking behavior and shift to nurturing instead. Large studies in 2005 and 2007 have identified the maternal line as the major contributor of male pattern baldness.
Hair normally lives for around five years. For People with male pattern baldness, the lost hair generally does not get replaced and this leads to baldness. Hair loss can begin in different areas but it is usually at the temples and at the crown of the head. It is seen that Testosterone, a male hormone which is present after puberty gets converted to dihydrotestosterone (DHT) by enzyme 5-alpha reductase. DHT affects hair follicles and slows down hair production.
Hair thinning and hair loss is high among black females and two thirds of African-American women by age 50 have experienced this problem. Continuous pulling of the hair from tight braids and weaves is considered as the main reason. There are other reasons such as excessive hot-pressing, curling or blow-drying, improper use of products could be some of the reasons. As the pattern baldness gets transferred to the male from the mother’s side, this pattern is observed in the black males also.
