Alopecia

Alopecia is the general term for hair loss on the scalp or body and does not refer only to alopecia areata.

Genetic factors, immune activity, hormonal changes, illnesses and certain medicines can contribute to different forms of hair loss.

Assessment includes an examination and, when needed, blood tests or a scalp biopsy.

Treatment depends on the underlying cause and may include topical or systemic medicines.

Early assessment matters in scarring forms because hair follicles can be permanently damaged.
