What causes Alopecia Areata, Totalis and Universalis?
The most current medical studies have concluded that these three types of alopecia are caused by an abnormality in the immune system.
The result is the immune system attacks particular tissues of the body. In alopecia, the affected hair follicles are mistakenly attacked in groups by a person's own immune system (white blood cells), resulting in the halt of the hair growth stage. These affected follicles become very small, drastically slow down prodution, and grow no hair visible above the surface for months or years. The scalp is the most commonly affected area, but the beard or any hair-bearing site can be affected alone or together with the scalp.
Studies have beeen done that show a genetic link for those people who are diagnosed as having alopecia. A good majority of those who develop alopecia have a hereditary gene that could be the possible cause of their hair loss.
Does psychological long-term stress and extreme shock tigger alopecia? Many people with new onset alopecia have had recent stresses in life, such as work, family, deaths, surgeries, accidents, etc.
