Androgenetic alopecia is the most common type of hair loss in both sexes. The hair follicles most typically subject to baldness are in the frontal and crown regions of the scalp, and this is related to the nature of the hair follicles (shorter longevity) themselves rather than the scalp anatomy.  In women, balding may also be a normal physiologic occurrence in those taking oral contraceptives or after parturition. Diffuse thinning over the entire scalp, with more noticeable thinning toward the front of the scalp, involving and sometimes breaching the frontal hairline is the most common type of baldness. 

Hair loss may affect other parts of the body other than the scalp, such as the eyebrow, moustache, beard, pubic area, and newly closed wounds; leading to serious cosmetic issues.
