Androgenic Hair Loss (Men & Women)
Androgenetic alopecia affects between 50 and 80% of Caucasian men. Generally 30% of men in their thirties, have androgenetic alopecia. For men in their forties, 40% have alopecia and so on until 80% of men are affected when 80 or more years old. Different ethnic backgrounds have different susceptibility levels towards the development of androgenetic alopecia. Black and Asian also have a lower incidence of androgenetic alopecia compared to Caucasians. These frequency differences between races suggests genetic predisposition is important in pattern baldness susceptibility.
Hair loss can often be observed in women in their late twenties to early forties, somewhat later in age than first onset in men. Unlike men the frequency of women affected does not continue to increase with increasing age. After the fifth decade of life the numbers of women with androgenetic alopecia does not increase. Androgenetic alopecia has been suggested to be present in the general female population at a rate anywhere between 20 to 40%. It is perhaps one of the best kept secrets that female androgenetic alopecia is so common
