I currently am using 5% minoxidil along with Revivogen. I usually apply the Revivogen just before bed about 2-3 hrs after I apply minoxidil. So, I go with: 1ml of minoxidil in the morning 1ml of minoxidil in the evening followed later by 1ml of Revivogen. and also nizoral 1% every 3 days I have used Minoxidil for years and never got any re-growth, but in the past two months since I have added Revivogen, I am starting to see some re-growth. Adding the Revivogen was the kicker, it seemed to have added some fuel to the fire so to speak. I am very happy with the combo so far.
