Alopecia areata causes loss of hair, leading to the formation of bald patches. One experiences an abrupt shedding of hair follicles, forming circular patches on the scalp.

Loss of body hair is a natural phenomenon. Alopecia patients experience more hair fall than hair regeneration. The condition causes bald patches in the scalp, leading to complete baldness in later years.

Alopecia is not limited to the scalp alone. Eyebrows and eyelashes, facial hair (for men), pubic hair, and body hair are affected over the years as well.

The types of alopecia include:

  • Alopecia Totalis:It leads to baldness and complete loss of hair from the scalp.

  • Scattered Alopecia:It is also known as diffused alopecia. In this type, marked thinning of hair follicles occurs without persistent hair loss.

What Leads to Alopecia Areata?

In Latin, Alopecia means "loss of hair", and Areata means "presence of patches". The sudden hair loss happens due to an auto-immune reaction where hair follicles are attacked indiscriminately. Alopecia areata begins as an isolated patch of missing hair that gradually grows in size, spreading all over the body.

Treating Alopecia Areata
