<p>Minoxidil stimulates hair growth by increasing oxygen, blood and nutrients supply to the hair follicle by widening blood vessels and inhibiting androgen hormone to affect hair follicles.<br />

Following topical application, an average of about 1.4% of the total applied dose is absorbed from the normal intact scalp. Topical Minoxidil absorption is increased by increasing the&nbsp; dose applied, increasing the frequency of dosing and decreasing the barrier function of the stratum corneum. Serum Minoxidil levels and systemic effects resulting from the administration of topical Minoxidil are governed by the drug&rsquo;s absorption rate through the skin. Following cessation of topical dosing, approximately 95% of the systemically absorbed drug is eliminated within 4 days. Minoxidil and its metabolites are excreted principally in the urine.</p>
