![]() ![]() About 30 percent of individuals who develop alopecia areata find that their condition either becomes more extensive or becomes a continuous cycle of hair loss and regrowth. People who experience just a few patches of hair loss often have a spontaneous, full recovery without any form of treatment. The hair follicles are not destroyed and so hair can re-grow if the inflammation of the follicles subsides. There may be itching or burning in the area before hair loss. The loss of hair can be sudden, developing in just a few days or over a period of a few weeks. Any site of hair growth may be affected, though, including the beard and eyelashes. Coin-sized patches of hair begin to fall out, mainly from the scalp. Most prominent symptoms of alopecia areata is patchy hair loss. Resources are also available to help people cope with stress related to hair loss. However, there are treatments that may help hair grow back more quickly and that can prevent future hair loss, as well as unique ways to cover up the hair loss. There’s currently no cure for alopecia areata. In all cases, hair regrowth may occur even without treatment and even after many years. No matter how widespread the hair loss, the hair follicles remain alive and are ready to resume normal hair production whenever they receive the appropriate signal. In others, extensive patchy loss occurs, and in a few, all scalp hair is lost (referred to as alopecia totalis) or, hair is lost from the entire scalp and body (referred to as alopecia universalis). Some people develop only a few bare patches that regrow hair within a year. 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. These affected follicles become very small, drastically slow down production, and grow no hair visible above the surface for months or years. In alopecia areata disease, the affected hair follicles are mistakenly attacked in groups by a person’s own immune system (white blood cells), resulting in the arrest of the hair growth stage. According to the National Alopecia Areata Foundation (NAAF) approximately 6.8 million people people in the United States and 147 million worldwide have or will develop alopecia areata at some point in their lives. The extent of hair loss and regrowth varies from person to person. When hair does grow back, it’s possible for the hair to fall out again. The condition can result in total hair loss, called alopecia universalis, and it can prevent hair from growing back. It can also develop slowly and recur after years between instances. Sudden hair loss may occur on the scalp, and in some cases the eyebrows, eyelashes, and face, as well as other parts of the body. The condition develops when the immune system attacks the hair follicles, resulting in hair loss. ![]() These patches may connect, however, and then become noticeable. It occurs in males and females of all ages and races, but onset most often occurs in childhood. The condition can affect anyone regardless of age and gender, though most cases occur before the age of 30. It usually starts with one or more small, round, smooth patches. Alopecia Areata OverviewĪlopecia areata is a common autoimmune disease that causes hair to fall out in small patches, which can be unnoticeable. The alopecia areata sera ( serum), plasma and peripheral blood mononuclear cells ( PBMC) biofluid are processed from patients peripheral whole-blood using customized collection and processing protocols. The alopecia areata fresh frozen biofluid samples are collected from unique patients diagnosed with alopecia areata disease and are provided to a valued pharmaceutical customer for research, diagnostics, discovery and drug development.ĭetailed clinical data, alopecia areata patients history, symptoms, complete blood count ( CBC), skin biopsy, histopathology, elevated biomarker levels, genetic and metabolic information associated with alopecia areata specimens is provided to a valued customer for research, development and drug discovery. The sera ( serum), plasma and PBMC biofluid specimens are processed from alopecia areata patient’s peripheral whole-blood using customized collection and processing protocols.
