I've been having trouble with my hair falling out in clumps. What's wrong with me?

It sounds like you may be experiencing a condition called alopecia areata, which is an autoimmune disease that causes hair loss. Alopecia areata can affect any hair on the body, including eyebrows and eyelashes. The cause of alopecia areata is unknown, but it is believed to be caused by a combination of genetic and environmental factors.
