Alopecia or Hair Loss: Description

Alopecia means loss of hair from the head or body. Alopecia can mean baldness, a term generally reserved for pattern alopecia or androgenic alopecia.

Alopecia or Hair Loss: Causes

Usually, most hair loss is not associated with systemic or internal disorder. Poor diet is rarely a contributive factor. Frequently, hair may simply thin as a result of predetermined genetic factors, family history, and the overall aging process.

Many men and women may notice a mild and often normal physiologic thinning of hair starting in their thirties and forties. Other times, normal life variations including temporary severe stress, nutritional changes, and hormonal changes like those in pregnancy, puberty, and menopause may cause a reversible hair loss.

Localized alopecia may be due to permanent skin damage (for example, by burns or radiotherapy) or trauma to the hair roots by styling or, rarely, trichotillomania. The most common type of localized hair loss is alopecia areata, which is an autoimmune disorder.

Alopecia or Hair Loss: Treatment and Diagnosis

There is no specific treatment, but the hair usually regrows within a few months. Alopecia universalis is a rare, permanent form of alopecia areata that causes loss of all the hair on the scalp and body, including the eyelashes and eyebrows. Skin diseases such as scalp ringworm, lichen planes, lupus erythematosus, and skin tumours may also cause localized hair loss. Treatments for male-pattern baldness include hair transplants or drug treatments with minoxidil or finasteride.
