Who is affected by hair loss
The most common cause of hair loss is inherited hair loss (androgenetic alopecia)—you inherit the tendency to go bald from either or both of your parents. About 50% of all people have this type of hair loss by about 50 years of age.1, 2
Hair loss may affect children as well as adults. Certain diseases, medications, or scarring can cause hair loss. Alopecia areata, which is hair loss caused by an autoimmune disease, affects about 1% of the population and occurs in children and adults.3 A fungal infection called ringworm of the scalp (tinea capitis) is very common in children and can also cause hair loss.
