I am 20 . im suffering from aga. using minoxidil 10. what should be my dosage once i grow sufficient amount of hair. i apply it twice daily as of now.

See details: Stay away from minoxidil. It is far from universally helpful and causes reduced testosterone and therefore often causes erectile dysfunction.

2 x day: If you grow hair with rogaine (minoxidil) and stop using it, you will lose the hair you grew with the product. This is one way to know if the rogaine (minoxidil) actually helped or if your hair loss would stabilize on its own. You could perhaps try 1 x daily, but you need to keep using it.
