SIMILAR TERMS
--------------------------------------

Alopecia Areata
A disorder in which the immune system attacks the hair follicles, causing loss of hair on the scalp.

Alopecia capitis totalis
Loss of all of the scalp hair. Alopecia means baldness and capitis refers to the head. Alopecia capitis totalis is thus total baldness of the scalp with normal hair elsewhere on the body.

Alopecia Mucinosa
A disease of the pilosebaceous unit, presenting clinically as grouped follicular papules or plaques with associated hair loss. It is caused by mucinous infiltration of tissues, and usually involving the scalp, face, and neck. It may be primary (idiopathic) or secondary to mycosis fungoides or reticulosis.

Alopecia totalis
An autoimmune disease similar to Alopecia Areata but that results in the loss of all hair on the scalp. It may begin as Alopecia Areata and progress into Alopecia Totalis.

Alopecia universalis
"Absence of all of the hair, not only on the scalp, but also on the entire body. Affected individuals are born without eyebrows and eyelashes and never develop axillary or pubic hair. There are hair follicles but they are devoid of hair. The disorder is inherited as an autosomal recessive trait. It is caused by a mutation in a gene dubbed HR in chromosome band 8p21.2 that is the human homolog of the mouse ""hairless"" gene -- the human version of the gene in the mouse that is responsible for hairless mice."

Alopecia, Male Pattern
Absence of hair from areas where it is normally present.

Alopecia, traumatic
Hair loss caused by injury to the scalp. Traumatic alopecia is usually caused by grooming methods that attempt to straighten the natural kinkiness of hair in order to make the hair more manageable. It is a result of stress traction injury from tight rollers and braiding as well as overheating the hair shafts. Vigorous combing and chemical bleaches and styling products can additionally irritate the scalp to cause further hair loss. Traumatic alopecia commonly occurs on both sides of the scalp and the broken-off hairs are frequently visible. Traumatic alopecia is treated by discontinuing the styling practices causing the hair and scalp injury. Partial or complete regrowth of hair can follow, but permanent loss of hair can occur when the roots of the hairs are severely damaged. To minimize risk of injury to scalp, if a person decides to continue or resume styling, it is best to use looser and larger wrapping and braids to reduce tension on the scalp and hair. Chemicals should only be applied to the hair and not the scalp directly. The hair should be unbraided at least every two weeks. Traumatic alopecia in the United States is a common form of hair loss in African-American women.
