Derma-rollers are something I’ve overlooked but seeing as how they’re so popular here I think I’ll give it a try. Thing is, I’m not quite sure how to tell if one is good or not. I did read that 0.5mm is the ideal starting size, used once a week, but other than that is there anything else I should know about? I’ve heard the titanium ones are better than stainless steel. Also, are the rollers better or worse than the derma stamps? I have large diffuse thinning, not just a local spot.
And does the brand matter? Any brand or model recommendations?
Microneedling is best done with a reciprocating needle device like the Dr. pen device, which has 36 needles and a depth of 1.25mm. Using once a week is the best way to go. You can hold it in a single area for a defined period, like 10 seconds, which delivers a known injury. This injury starts a healing cascade that brings in or activates the stem cells found in the upper part of the hair follicles or in the upper part of the dermis at a depth of about 1 mm.
