Featured patient discussions on alopecia areata "My alopecia first started two months before I conceived my son who is now 5 years old. My hair grew faster after I had my son. I used an ointment and herbal oils, which also helped a lot. There were times when I oiled my hair whenever I had to wash, so every two days or so. After giving birth and weaning my son, I got cortisone shots when the hairless patches recurred. Whenever I would have a disagreement with my husband over something, my scalp became itchy, the hairless patches appeared again. Recently when we were at the verge of a divorce, I had four hairless patches. I saw a dermatologist, and he gave me the cortisone shots again, it stimulated the hair growth. He also gave me an ointment that soothes my scalp. I think alopecia areata is mainly related to emotional stress. I am trying to be positive, and have become more close to God by praying regularly. That helps me calm down and release my stress. I hope someone can benefit from this."

What is alopecia areata?

Alopecia areata is a hair-loss condition which usually affects the scalp. It can, however, sometimes affect other areas of the body. Hair loss tends to be rather rapid and often involves one side of the head more than the other.

Alopecia areata affects both males and females. This type of hair loss is different than male-pattern baldness, an inherited condition.

What causes alopecia areata?

Current evidence suggests that alopecia areata is caused by an abnormality in the immune system. This particular abnormality leads to autoimmunity. As a result, the immune system attacks particular tissues of the body. In alopecia areata, for unknown reasons, the body's own immune system attacks the hair follicles and disrupts normal hair formation. Biopsies of affected skin show immune cells inside of the hair follicles where they are not normally present. What causes this is unknown. Alopecia areata is sometimes associated with other autoimmune conditions such as allergic disorders, thyroid disease, vitiligo, lupus, rheumatoid arthritis, and ulcerative colitis. Sometimes, alopecia areata occurs within family members, suggesting a role of genes and heredity.

What are the different patterns of alopecia areata?

The most common pattern is one or more spots of hair loss on the scalp. There is also a form of more generalized thinning of hair referred to as diffuse alopecia areata throughout the scalp. Occasionally, all of the scalp hair is lost, a condition referred to as alopecia totalis. Less frequently, the loss of all of the hairs on the entire body, called alopecia universalis, occurs. Sometimes the hair loss can involve the male beard, a condition known as alopecia areata barbe.
