ETYM Latin alopecia, Greek alopekia, from alophx fox, because loss of the hair is common among foxes.

Patchy baldness, baldness. alopecia areata, loss of hair in small patches.
Another name for baldness.

Loss of hair from the scalp, common in older men. Its onset and extent are influenced by genetic makeup and the level of male sex hormones.

Alopecia, a condition in which the hair falls out, is different from the “male-pattern baldness” described above.
