Vasodilators relax arteriolar smooth muscle, causing vasodilation; hair growth effects are secondary to vasodilation.

Minoxidil topical (Rogaine Extra Strength)

Minoxidil stimulates hair growth in general and is effective in many types of hair loss. The exact mechanism of action remains unclear, but it does not appear to have either hormonal or immunosuppressant effects. The 5% solution appears to be more effective.
