How does Minoxidil work against hair loss?
Minoxidil was initially used to treat high blood pressure, but when researchers discovered that one of its side effects was increased hair growth, it was also used to treat hair loss.
There is no exact explanation as to why the drug works against hair loss. The theory is that the area being treated receives more oxygen and nutrients, causing the blood vessels at the hair follicles to dilate and more hairs to be produced.
