Got my roller in today. Just gave it a test run, not quite as hard as I"m supposed to go but wanted to test my skins response before I go all in. Pain is a bit borderline, on the scalp it is tolerable, almost invigorating but on the bare temples it's a bit too sharp, I'll have to pick up a cream. It feels like you don't need alot of pressure actually though, for me, as soon as I apply a small/medium amount I'm definitely getting the popping sound and applying harder doesn't make a difference so I'm guessing I'm hitting full depth pretty easy. I got the 192 needle 1.5 mm one off amazon. I only went long enough to get 7 or 8 bleeders, once I get the cream I'll go a bit harder. This is good because I feel like with minoxidil lately I have been losing some progress, I'm still above my base line from almost two years ago which is a big positive but not as good as I was 6 months after starting minoxidil. I will take some pictures for you guys, probably bi-weekly or so.
