Thanks! From briefly researching I think I will just buy a derminator, it can be used for skin tooDepends on what you want to do imo, if you want to follow the original posters regimen or follicas method use a pen, dr pen ultima a6 is a good choice, however if you want to use daily a roller is better, i have seen really great results from daily mild rolling just before applying minoxidil, chens results comes to mind.
