Definition and Symtoms

Alopecia, commonly known as baldness, is a set of disorders which involves the state of lacking hair where it would normally grow, especially on the head. The most common form of baldness is a progressive hair-thinning condition that occurs in adult humans and other primate species. Nonetheless, the severity and nature of condition can vary greatly; it ranges from male and female pattern alopecia (alopecia androgenetica), to alopecia areata, which involves the loss of some of the hair from the head, alopecia totalis, which involves the loss of all head hair, to the most extreme form, alopecia universalis, which involves the loss of all hair from the head and the body. Treatment for alopecia has limited success. The more hair lost, the less successful the treatment will be.

What are the main symptoms?

Male pattern baldness (also known as genetic hair loss or alopecia androgenetica) is the most common form of hair loss in men. It usually develops very gradually, typically involving the appearance of a bald spot on the crown of the scalp accompanied by thinning at the temples. Although this problem can strike any man at any time, many first become aware of it as they approach their thirties.
