I use a 1.5mm derma stamp and I definitely draw blood to ensure that I have done adequate damage to a given spot. They say never apply minoxidil within 24 hours of micro needling with longer needles, but I'm unsure why. I've been doing it and I dont notice any negative effects so I don't really care unless there's a very serious reason not to, such as subtle effects on the heart that can cause serious damage later on.
