The following hair disorders may result in partial or complete hair loss:

• ANDROGENETIC ALOPECIA
  A genetic disorder and the most common form of women's hair loss. Androgenetic Alopecia is characterized by diffuse hair loss over most of the scalp. It is a progressive condition for which there is no known cure.
• ALOPECIA AREATA
  Mild, patchy hair loss on the scalp. Alopecia Areata is thought to be an auto-immune disorder in which the body's own immune system perceives the hair follicles to be foreign and attacks them. There are a number of treatments for this condition but no known cure.
• ALOPECIA TOTALIS
  A condition in which all or most of the hair on the scalp falls out.
• ALOPECIA UNIVERSALIS
  A condition in which all or most of the hair on the scalp and body falls out.
• TRICHOTILLOMANIA
  Self-induced hair loss resulting from continuous pulling of the hair. It may be consciously or unconsciously self-inflicted. Trichotillomania occurs most commonly among young children, adolescents and women. Treatment may involve counseling and psychiatric help, and antidepressants may be prescribed.
• TELOGEN EFFLUVIUM
  An acute disorder caused by sudden and severe stress. The hair may stop growing for a period of time, then begin to fall out. Telogen Effluvium is a temporary condition often precipitated by childbirth, birth control pills, medication or severe emotional distress.
• ANAGEN EFFLUVIUM
  Hair loss caused by exposure to certain chemicals and radioactive substances. Cancer patients undergoing chemotherapy or radiation treatment often experience this temporary disorder. When treatment is stopped, the hair follicles recover and the hair grows back.

You should consult your doctor with specific questions you may have about your hair loss condition.
