What is Minoxidil?
In the past, Minoxidil was used as a medicinein tablet form to treat high blood pressure. When it was noticed that people treated with Minoxidil had excessive hair growth (hypertrichosis), Minoxidil also began to be used to stimulate hair growth.
Today, the drug is available in hair mousse, liquid and tablet form and is sold as a treatment for male and female hair loss.
The amount of Minoxidil absorbed through the skin into the bloodstream is usually so small that it does not cause any internal side effects.
