Dude, I do not want to argue with you, but after seeing some of your comments I feel I need to step in for your own good and also for others who might actually get to the point of believing that needling is a 100% cure/solution for hairloss.
I really dont know why you find it hard to believe that microneedling doesnt work for everyone. You've said in other posts that you havent hear of or read any account claiming that needling didn´t work. It seems to me that you haven't read previous large threads in this and other fórum about dermarolling community trials. There were A LOT of dudes whinning and complaining that "this sh*t ain't working". Why? Probably because of two alternate scenarios 1) they were not patient enough and just did it for like 3-9 months (results MAY come a bit later for slow responders), 2) it simply DOESN'T work for everyone, regardless of for how long you wound. We still don´t know, can be any of the two. But do the exercise and check the very large threads back then. They are large, so it can take you a while to check the them completely, but you well get a decent amount of info and you see that it is incompatible with the way you claim that microneedling is the holy grail.
Don´t get me wrong, I am a needling enthusiast, I'm commited to needle for at least a year or more even if I dont see early regrowth, and I think EVERYONE losing hair should give it a try, given that the evidence behind it's success is solid, but that doesn´t mean in ANY POSSIBLE WAY that it is imposible for someone not to respond to this relatively new and understudied treatment. As with almost anything, you Will always find someone who doesnt respond to X or Y treatment. Happens with finasteride, happens with minoxidil.
Let´s all give it a try and remain possitive, but let´s not be somewhat fanatical about it. Contempling the worst case scenario is always a healthy thing to consider to avoid a huge disappointment and psychological impact
