Can you water down extra strength minoxidil? I can buy Extra Strength Regaine (5%) at about the same price as standard 2% stuff. I probably dont need extra strength but it was all I could buy at the time at the price. I am currently unsing half the amount of 5% and it seems to be working ok with Finasteride. ( posting.php?mode=reply&f=28&t=48040 ) Can it be diluted with water? to go further?
