The compulsive pulling of one’s own scalp or body hair. Sometimes it is moderately managable, but other victims find the compulsion to pull out their hair completely uncontrollable and thus devestating to their lives.
Example: A physician notices a peculiar pattern of hair loss, which the patient admits was caused by her habit of pulling at her hair.
