Oral Minoxidil; Safe Dose

Basics of Minoxidil

Minoxidil is a piperidinopyrimidine derivative. It is a potassium channel opener, and the main function is a vasodilator.
However, hair doesn’t grow even if skin blood flow is increased by the action of vasodilators. 

Minoxidil is a prodrug and it doesn’t have any pharmacological action.
Minoxidil is changed to minoxidil sulfate by the enzyme in the scalp. The name of the enzyme is minoxidil sulfotransferase.

Minoxidil sulfate is an active form of minoxidil. Minoxidil sulfate stimulates hair regrowth, and it increases the number of hair follicles in the mid and late anagen phase.
