Alopecia usually starts with a bald patch, which often disappears within six months to two years. Sometimes two patches can merge together and wider areas will be affected. In some cases total baldness may occur.
There is no way at present to predict the course of alopecia in individual clients. Research suggests that 65% of people will experience one or two patches of hair loss while 35% will experience more persistent hair loss. Approximately 7% will experience total hair loss.
