Frequency and Prevalence

Men

Male AGA occurs in all populations. The prevalence is highest in Caucasians, reaching around 80% in men aged over 70 years.[5,6] In the Asian population, a prevalence of 46·9–60·0% has been reported in males older than 70 years.[3,7] There is scant published information on the frequency of balding in African men. One older study reported that balding is four times less common in African-American men than in Caucasians. The frequency and severity of male AGA increase with age in all ethnic groups.[2,3] Initial signs of AGA, including some recession of the frontal hair line and at the temples, usually develop during teenage years. Progression to deep frontal recession and/or vertex balding may also start shortly after puberty, although in most men the onset is later. By the age of 70 years, 50–60% of Caucasian men are bald (Hamilton–Norwood VI–VII).[2,6]

Women

As in men, the population frequency and severity of AGA increase with age in women.[5] Two studies in Caucasian women in the U.K. and the U.S.A. reported prevalence rates of 3–6% in women aged under 30, increasing to 29–42% in women aged 70 years and over.[8,9] The frequency is lower in Oriental women compared with those of European descent.[3] There are no published data on the frequency of AGA in African women.
