Female pattern hair loss can begin at any age from teen-age
through middle age. There may not be an obvious hereditary association; whereas
a man with AGA usually has close male relatives with AGA, no such family
pattern may be apparent for women.
While AGA is the most common cause of permanent hair loss in
women (about 50 percent of women over age 40 have some degree of female pattern
hair loss), it is by no means the only cause. Non-AGA causes of hair loss are
more frequent in women than in men; some of these causes are discussed in the
next section.
Women more than men are also likely to have temporary hair
loss that may occur separately or together with female pattern hair loss. Two
common causes of temporary hair loss in women are the hormonal changes
associated with pregnancy and untreated hypothyroidism.
A woman who is worried about loss of scalp hair should
consult a physician hair restoration specialist for evaluation and diagnosis.
Female hair loss can usually be successfully treated after a diagnosis is
established.
