Alopecia areata is a hair-loss disease that affects more than 1 million people in a year globally. It is an autoimmune disease where the immunity system attacks the hair follicles causing the hair to fall out in lumps. The hair fall is such that it causes baldness in a coin-shaped pattern on the scalp. The amount of hair loss differs from patient to patient. Some individuals lose hair only in a few spots, whereas others lose a lot of hair. It can affect anyone irrespective of the gender or age factor, although the chances are that one will encounter it before the age of 30.

- Alopecia Totalis: In this type of alopecia, loss of hair occurs on the whole scalp.
- Alopecia Universalis: This form of alopecia is more advanced than alopecia totalis wherein hair loss occurs across the whole body including the scalp, face, and pubic area.
- Persistent patchy alopecia areata: It is identified by patchy hair loss on the scalp that remains for a considerable amount of time without developing into alopecia universalis or totalis.
