I don’t think there should be that much blood. What needle length are you using?I'm not trying to answer your question. Just asking: How goes your needling with hair that long? I mean, with that hair lenght you can do some needling, but not enough, as the blood gets tangled up in your hair making it hard to see what you're doing, and the hair might get in the way too. I always trim my hair to #0 before needling so washing away the blood and applying minoxidil are also very easy.
