5% minoxidil 1x daily, 1mL, some days I use liquid, others foam. Dermaneedling 2x weekly, once lightly with 1mm, once with firmer pressure at 1.5mm, have never bled.. I only needle until I get a uniform mild redness. All over crown and hairline. I don't wait 24 hours to apply minoxidil. But I do wait a bit. Usually around 4-5 hours. No sides. Used rollers in the beginning, but now I have a Derminator.
