Hirsutism is defined as excessive hair growth in both a normal and an abnormal distribution [13]. Most pregnant women develop
some degree of hirsutism, which is usually most pronounced on the face (upper lip, chin, and cheeks). The arms, legs, and
back can also be involved (Figs. 3.1, 3.2) [22, 23]. In addition, suprapubic midline hair growth with a male-pattern distribution
may also be increased during pregnancy [5, 23]. Acne may be an accompanying feature of hirsutism [23].
Hirsutism generally starts early in pregnancy, and is usually more pronounced in women with preexisting abundant body hair
or very dark hair or in women with a preexisting tendency toward a male pattern of hair distribution [4, 23]. Within 6 months
postpartum and even before delivery, most of the excess fine lanugo hairs disappear, but coarse and bristly hair usually remains.
Recurrence with subsequent pregnancies is common [23].
