Manufacturers note that minoxidil-induced hair loss is a common side effect and describe the process as “shedding”.
Alcohol and propylene glycol present in some topical preparations may dry the scalp, resulting in dandruff and contact dermatitis.
Some formulations of minoxidil substitute lipid nanosomes in order to reduce contact dermatitis from the alcohol and propylene glycol vehicle.
Oral minoxidil side effects may include swelling of the face and extremities, rapid and irregular heartbeat, lightheadedness, cardiac lesions, and focal necrosis of the papillary muscle and subendocardial areas of the left ventricle.
