The duration for which topical minoxidil should remain on the scalp following application is a critical factor influencing its effectiveness in promoting hair regrowth. This timeframe allows the medication to be absorbed into the hair follicles, where it exerts its vasodilatory and proliferative effects. Insufficient contact time may limit absorption and reduce the potential benefit of the treatment.
Adhering to the recommended application duration is important for maximizing the therapeutic potential of minoxidil. This practice contributes to improved hair density and reduced hair loss over time. While variations in application method or product formulation may exist, the core principle of allowing sufficient contact time remains a cornerstone of successful minoxidil therapy.
