Hair Loss and Wigs

Hair loss or baldness (technically known as alopecia) is a loss of hair from the head or body. Baldness can refer to general hair loss or male pattern baldness specifically. Some types of baldness can be caused by alopecia areata, an autoimmune disorder. The extreme forms of alopecia areata are alopecia totalis, which involves the loss of all head hair, and alopecia universalis, which involves the loss of all hair from the head and the body.

Baldness can have many causes, including fungal infection (tinea capitis), traumatic damage, such as by compulsive pulling (trichotillomania), as a result of radiotherapy or chemotherapy, and as a result of nutritional deficiencies such as iron, and as a result of autoimmune phenomena, including alopecia areata and hair loss associated with systemic lupus erythematosus.

A wig is a head covering made from human hair, animal hair, or synthetic fiber that is worn for fashion or other reasons, including cultural tradition and religious observance. The word wig is short for periwig and first appeared in the English language around 1675.

Some people wear wigs to disguise baldness; a wig may be used as a less intrusive and less expensive alternative to medical therapies for restoring hair. Wigs may also be used as an article of apparel, or to fulfill a religious obligation. Actors often wear costume wigs in order to portray characters.
