Alopecia areata is a type of hair loss that occurs when the immune system mistakenly attacks hair follicles, place where the hair growth begins. The damage to the follicle is usually not permanent. But the cause of the immune system attacks the follicles is unknown. Alopecia areata is most common in people younger than 20, but children and adults of any age may be affected. Women and men are affected equally. Alopecia areata usually begins when clumps of hair fall out, resulting in totally smooth, round hairless patches on the scalp. In some cases the hair may become thinner without noticeable patches of baldness, or it may grow and break off, leaving short stubs. In some rare cases, complete loss of scalp hair and body hair occurs. The hair loss often comes and goes but, hair will grow back over several months in one area but will fall out in another area. When alopecia areata results in patches of hair loss, the hair usually grows back in a few months. Although the new hair is usually the same color and texture as the rest of the hair, it sometimes is fine and white. About 10% of people with this condition may never regrow hair.
Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article. Together, journal articles in a particular field are often referred to as The Literature. Journal articles are most often Primary Research Articles. However, they can also be Review Articles. These types of articles have different aims and requirements. Sometimes, an article describes a new tool or method. Because articles in scientific journals are specific, meticulously cited and peer-reviewed, journal databases are the best place to look for information on previous research on your species. Without a background in the field, journal articles may be hard to understand - however, you do not need to understand an entire article to be able to get valuable information from it.
