How
common is pattern baldness in Caucasian men
There are no extensive research studies to define the frequency
of male pattern baldness. However casual observation suggests that
the incidence in the Caucasian population is very high. Some dermatologists
(Dawber) suggest that hair loss can begin in teenage years for some
men and the frequency in elderly male Caucasians reaches almost
100%.
However, this figure may be on the high side. Examing, classifying,
and recording hair loss is a very subjective method and while some
dermatologists record even the slightest apparent hair loss others
ignore slight loss as not being due to androgenetic alopecia. More
typically androgenetic alopecia is reported as affecting between
50 and 70% of Caucasian men and 40 to 50% of women. A rough and
ready rule is that for men in their thirties, 30% have androgenetic
alopecia. For men in their forties, 40% have alopecia and so on
until 70% of men are affected when 70 or more years old.
