This means hair loss due to male-pattern baldness and is seen in both men but also in post menopausal women .
This term describes normal hair loss which occurs in men from early adult life and in women from the menopausal years. In other words, both men and women lose their hair as time goes by but men start to lose their hair at a much earlier stage. Very elderly women almost always have a reduced hair density. A variety of internal medical disorders can mimic this type of problem and it is sometimes worth considering blood tests for these disorders.
