Hair Loss
Most people shed between 50 and 100 hairs daily.
Normal hair shedding can occur due to a variety of reasons but typically resolves itself after a few months. Excessive hair shedding (beyond 100 hairs per day) may be caused by a medical condition related to stress called telogen effluvium.
Hair loss can have a variety of causes such as alopecia areata — a disease in which the body attacks its own hair follicles. Other types such as female pattern hair loss, and male pattern hair loss can occur due to heredity.

The use of certain medications, hormonal imbalances (after a woman gives birth), age, and underlying disease may also also be the cause of hair loss.
Hair loss symptoms vary depending the cause. Some types of hair loss can be treated. It is important to determine the cause of hair loss in order to properly treat it.
