I tried to be smart and used 2 mls (1 ml didn't cover the needed areas as it's hard to get into long hair) of 5% minoxidil 2x per day which was all good until my body's vellus clear hairs started turning black and it's not something that I can handle removing every little while so I might be reducing the dose to control this, so ladies just stick to once per day and don't do what I did
