Alopecia Totalis is one of a group of three main conditions. Those three are Alopecia Areata, Alopecia Universalis, and of course Alopecia Totalis (AT). AT is an auto-immune disorder which results in the total loss of hair, but only on the scalp. It is somewhat of an intermediary condition between Alopecia Areata which is patchy scalp hair loss, and Alopecia Universalis which extends to total body hair loss. AT usually appears in two types: One being a fairly sudden and complete loss of all head hair. The other being a slower form which originates as Alopecia Areata (patchy loss) and advances to complete scalp hair loss. In this sense it is sometimes tied to Alopecia Areata (patchy loss), but not all the time.
Most sufferers are children and young adults under the age of 40, though it can affect people of all ages. It can also affect the the nails, giving them a ridged, pitted or brittle appearance. According to statistics, 2% of men and 1% of women in western society suffer from some form of Alopecia Areata. About 2% of those have Totalis or Universalis. This means that about 1 in every 125,000 men and 1 in every 250,000 women have Alopecia Totalis or Universalis.
