I started derma rolling like four weeks ago and have already had significant regrowth on hairline. I buzzed my head short to start minoxidil + dermarolling with a 1mm 500somthing needle roller and it's been pretty good so far. My crown is filling in as well. I have diffuse thinning so I pretty much dermaroll my entire head lol, never any blood, only mild erythema despite applying firm pressure. My derminator is coming sometime in January, which I'm really excited about. Anyway, I tried minoxidil about a year ago for some months but never got anything out of it, so I'd have to attribute the new hairs I see to the disruption of the epidermis that's happening with the dermaneedling. Also I took finasteride for like seven months and got literally nothing out of it except an intermittently dead penis tbh
I don't have any baseline pics
but the temple areas in these photos were pretty bald:
