About Alopecia Areata
Alopecia areata is an autoimmune condition where the immune system mistakenly fights the hair follicles from which hairs grow. The consequences of this disease include hair loss on the head and in some cases, in other places on the body such as the pubic region, eyebrows, eyelashes etc.
Generally, the hair falls in a few smaller round patches. Although in some people hair loss can be larger, the condition usually does not surpass beyond these bare patches. It is possible for the disease to lead a total loss of hair on the head (alopecia totalis) or complete loss of hair on the face, head and body (alopecia universalis).
Causes and symptoms of Alopecia areata
The immune system cells, called as white blood cells fight the speedily growing cells in hair follicles, which is where the hair is made. New air production slows down due to the smaller size of these hair follicles. Stem cells feeding the hair follicle with new cells are not targeted is the known fact and the follicle is usually not permanently damaged and can eventually re-grow hair normally

The exact reason for why air hair follicles go through these changes is also unsure by experts, it is questionable that it may be a combination of genes that can predispose certain people to this particular disease. Certain triggers such as viruses, environmental factors or emotion are the resources for those who are predisposed to Alopecia areata. Any of these factors can be supposed for an attack against the hair follicles. One cause for developing the disease is the hereditary problem.
The source of Alopecia areata
Family members who have lost their first patch of their hair before 30 years of age are the sources for the disease and other of their family members are also in a greater risk of developing Alopecia areata. Scientists claim that one in five people who suffer Alopecia areata have a family member who also has the same problem.
