Alopecia areata is a form of hair loss from areas of the body, usually from the scalp. Because it causes bald spots on the head especially in the first stages, it is sometimes called spot baldness. In 1–2% of cases, the condition can spread to the entire scalp (alopecia totalis).
Androgenetic alopecia (also known as androgenic alopecia or alopecia androgenetica) is a common form of hair loss in both men and women. In men, this condition is also known as male-pattern baldness. Hair is lost in a well-defined pattern, beginning above both temples. Over time, the hairline recedes to form a characteristic “M” shape. Hair also thins at the crown (near the top of the head), often progressing to partial or complete baldness.
The pattern of hair loss in women differs from male-pattern baldness. In women, the hair becomes thinner all over the head, and the hairline does not recede. Androgenetic alopecia in women rarely leads to total baldness. A variety of genetic and environmental factors likely play a role in causing androgenetic alopecia.
