Hair shedding can sometimes temporarily increase when starting minoxidil or PRP as old hairs make way for new growth, and visible results often take six months or more. For your dandruff, ensure you leave the Nizral (ketoconazole) shampoo on your scalp for five minutes before rinsing so it can work effectively. Persistent symptoms might mean there is an underlying scalp inflammation or hormonal factor that needs a different approach. Consult your dermatologist to tailor your treatment plan for the best results.
