What can cause your hair to fall out in clumps?

* Telogen effluvium: This is the most common cause of hair loss in clumps. It occurs when a large number of hair follicles enter the resting (telogen) phase at the same time. This can be caused by a variety of factors, including stress, illness, childbirth, and certain medications.

* Androgenetic alopecia: This is a genetic condition that causes hair loss in men and women. It is often referred to as male-pattern baldness or female-pattern baldness. Androgenetic alopecia is caused by a combination of factors, including genetics, hormones, and aging.

* Alopecia areata: This is an autoimmune condition that causes hair loss in round or oval patches. Alopecia areata can affect the scalp, eyebrows, eyelashes, and other areas of the body. The exact cause of alopecia areata is unknown, but it is thought to be related to the immune system attacking the hair follicles.

* Traction alopecia: This is a type of hair loss that is caused by pulling or tugging on the hair. Traction alopecia can be caused by hairstyles that put tension on the hair, such as tight braids or cornrows, or by using harsh chemicals or heat styling tools.

* Tinea capitis: This is a fungal infection of the scalp that can cause hair loss. Tinea capitis is also known as ringworm. It is spread through contact with an infected person or animal.
