What is minoxidil?
Minoxidil (2,4-diamino-6-piperidinopyrimidine 3-oxide) was originally used orally as blood pressure medication. Its primary use was thus for treatment of patients with high blood pressure when it was administered as oral medication.
This means that minoxidil is an antihypertensive vasodilator which is used to treat hypertension.
Over the years, it has been found that minoxidil is also effective for preventing hair loss, but more importantly, for growing back hair when minoxidil is administered topically in foam or liquid form.
