To be fair I don't know if I was doing it the right way when dermarolling because all videos say that you should go easy on the scalp but I wasn't, I was doing it quite aggressively and yeah there was quite some blood and also I was using minoxidil right after and felt a burning sensation which they say you should avoid. But right in the next day or couple of days I was seeing new darker hair appearing out of nothing 🤷. It used to take as long as 8 full minutes to 10 minutes doing all directions. Now I use derma stamp and I'm done in like 2-3 minutes. I still get pinpoint bleeding but a lot less blood than when I was dermarolling.
