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.
Medications are designed to treat a variety of health conditions, but sometimes they can have unwanted side effects. Certain drugs can contribute to excess hair growth, changes in hair color or texture, or hair loss.
Drug-induced hair loss, like any other type of hair loss, can have a real effect on your self-esteem. The good news is that in most cases, it's easily reversible once you stop taking the drug.
