Also, microneedling can heal really bad scarring very, very well. It seems to have youth and healing effects on all tissue and I am willing to bet that shrink donor area scarring and also cobblestone or baby doll hairline scarring. Grafts that had given up the ghost now appear to all lie flush and are productive of excellent hair not the eh hair from transplants for diffuse thinners like me. I do it weekly on ever single cm of my body above the ahem, tits. Yes, I tried rolling them too but the pain was too great to do it much there.
