So I'm in on this. I did it for the first time last week, and I have a couple questions. I'm sure they've been asked a 100 times already, but unfortunately I don't have the time to read a almost 300 page thread 
- How long should I do it? I'm rolling hard, the pain is noticeable but bearable. I'm definitly getting in deep, and my scalp has had some bleeding all over. Is this too much, enough, or too little?
- When preparing and cleaning the roller afterwards I wash it with hot water, then soak it in isopropanol 70% for about 10 minutes each. Is this ok, or unhygienic?
- Do I need to replace the roller after a certain amount of applications? If yes, how many?
Thanks in advance!
