Hair Loss Disease

By admin

Alopecia is the medical term for hair loss. Alopecia Areata is the most common form of an unusual auto-immune skin disease resulting in patchy hair loss on your scalp. It usually starts with a small patch of hair loss and continues with one or more small, round patches of hair loss on your head. Hair growth is a repeating cycle that can be disrupted by genetics, diseases, medications, infections or other more common factors that may cause hair loss. During the anagen growth phase, a follicle actively grows hair until the catagen phase in which the follicle slows down growth. During the telogen phase, the follicle rests prior to the start of a new anagen phase or growth of a new hair shaft. As the new hair shaft pushes out the ‘dead’ hair shaft, the old hair is shed. “About 50 to 100 telogen hairs are normally shed every day and you find them in your comb, brush and shower drain,” says Dr. Wasserbrauer. About 10 percent of scalp hair follicles are normally in telogen phase at any given time if the scalp is healthy and not affected by any condition that causes hair loss.

The first is Alopecia Areata which presents as random patches of hair loss. When hair loss involves the total head, it is called Alopecia Totalis and when it extends to the total body hair loss it is called Alopecia Universalis, There is no sure cure for the conditions but many doctors prescribe medications to help control the episodes. In all forms of Alopecia, the hair follicles remain alive and are ready to resume normal hair production whenever they receive the appropriate signal from the body.
