Inpatient & Outpatient Medications
Although topical minoxidil is not effective in preventing chemotherapy-induced alopecia, it shortens the period of baldness by about 50.2 days.
Deterrence/Prevention
The application of a pressure cuff around the scalp and local hypothermia retard anagen arrest, if these measures are implemented during the infusion of the causative medication (see Medical Care).
The discontinuation or avoidance of the causative drug reverses anagen effluvium.
Bleiker et al did not achieve success in a trial of the possible prophylactic effects of pretreatment with calcipotriol before chemotherapy.
Prognosis
Anagen effluvium is entirely reversible, with hair regrowth typically occurring after a delay of 3-6 months.[2] Upon the cessation of drug therapy, the follicle resumes its normal activity within a few weeks. Mitotic inhibition apparently stops the reproduction of matrix cells, but it does not permanently destroy the hair. In some cases, hair regrows despite continued or maintenance therapy. On occasion, the color and texture of the hair that regrows after chemotherapy-induced alopecia is different from those of the original hair.
Patient Education
Drug-induced alopecia can be psychologically devastating to a patient. Patients have even refused possibly palliative or life-saving treatments because they could not accept the temporary or prolonged baldness.
Patients must be warned of the potential for hair loss when they undergo treatment with any of the medications responsible for anagen effluvium (see Causes).
Patients should also be reassured that the hair loss is temporary. Normal hair growth resumes a few weeks after the termination of treatment, although the color or texture of the regrowing hair may differ from those of the original hair.
