Areata is especially related to autoimmune
factors with its aggravation being influenced by the emotional state. Alopecia
areata is characterized by rapid, partial or complete loss of hair in one or
more areas of the scalp or in areas such as beard, eyebrows, pubis, etc. Hair
regrowth can occur spontaneously in a few months, but in some cases the disease
progresses, affecting the entire scalp (alopecia total) or the entire body
(alopecia universalis).
