Alopecia Areata

Alopecia areata strikes suddenly, without warning. It can affect both sexes at any age. In some cases it develops into loss of all scalp hair (alopecia totalis) or into the loss of all body hair including that on the scalp (alopecia universalis). It is estimated that about one-fifth of all cases will go on to become alopecia universalis.

Alopecia areata - the words are taken from the Greek meaning "mangy fox" - appears suddenly and unexpectedly. For the past 60 years this disease has been on the increase. It now affects at least one in 100 people throughout the world, according to an epidemiological study carried out in Rochester, Minnesota, by leading American dermatologist Professor Sigfrid A. Muller of the Mayo Clinic. He predicts a similar increase over the next five decades.
