Tag: Scalp absorption

Only about 1.4% of topically applied minoxidil is absorbed through a normal, healthy scalp. This surprisingly low figure highlights the specific and localized way the medication is intended to work, directly answering the question: does your scalp absorb minoxidil, and if so, how does that minimal absorption drive hair regrowth?

According to a 1990 study, approximately 75% of minoxidil applied topically to the scalp is absorbed within four hours. Understanding **how long does it take for your scalp to absorb minoxidil** is crucial for maximizing the effectiveness of this popular hair loss treatment.
