Treatment of permanent chemotherapy-induced alopecia with low dose oral minoxidil.

Chemotherapy-induced alopecia is a well-established cause of major distress to patients. Permanent chemotherapy-induced alopecia (PCIA) is the absence of or incomplete hair regrowth lasting longer than 6 months after the cessation of chemotherapy and it does not respond to standard treatments of scalp cooling or topical minoxidil. The increasing numbers of reports of PCIA highlight the need for research into an effective treatment. We report a case of a 39 year-old woman with cosmetically significant regrowth after continuous therapy with oral minoxidil.
