How Many Types of Hair Loss?

Alopecia Areata — Alopecia areata is an autoimmune disease in which the immune system falsely attacks the hair follicles. The result is hair loss in small circular patches around the head that can spread and combine to cause larger patches. Researchers believe that some type of trigger, such as a virus or vitamin deficiency, may bring on the attack.

Male Pattern Hair Loss — Male pattern hair loss is also known as androgenic alopecia. The most common type of hair loss in men, passed through genetics and family history.

Female Pattern Hair Loss — Female pattern hair loss occurs when hair follicles shrink over time. For women with female pattern hair loss, the new hair is finer and thinner. This can be caused by aging, changes in androgen (male hormone) levels, or a family history of male or female pattern baldness.

Telogen Effluvium — Telogen effluvium is the second most common form of hair loss, and it’s considered as different phases of the hair growth cycle. The telogen phase is when the scalp does not produce hair; it’s also known as the resting phase. Typically, 80 percent to 90 percent of the hair follicles are growing at one time, but with telogen effluvium, the number of hair follicles producing hair drops significantly during the resting phase, resulting in shedding or hair loss.
