Microneedling? No.
The delusions of people who try to justify DIY not working? Hell yes.
You're really bad at understanding this.
3-4 months is the amount of time it has generally taken in any study to see obvious results. You expect me to believe that after 3 fuckin' months of following the protocol to the best of my ability, and ensuing 5 months there after, that I actually just had to keep rolling for six months straight and then I'd have total regrowth?
That's not how this works. Wounding is supposed to create new hair. That means that, if after several months, none of that vellus hair has grown, then it means no terminal hair has grown. No amount of rolling from that point is going to magically make that vellus hair grow.
Just accept that it didn't work for you, and wait until the professionals who've spent a decade studying this sh*t show what they can do.
Face it: 9/10 of you, to be generous, are going to fall silent in that thread within six months. No photos. Nothing, because it didn't work on any worthwhile level.
