Evidence of Chronic Sun Damage
Hair protects us from the sun and from the damaging effects of ultraviolet radiation. It's clear that the risk of skin cancer is increased in males who are balding compared to males who are not balding. The typical signs of sun damage are seen in the photo and referred to as "dyschromia" and include dilated blood vessels (number 1) as well as pigmentation changes (number 2). Dyschromia from sun damage includes both hypopigmentation (lighter colors) and hyperpigmentation (darker colors).
