Yes, and maybe. I do nothing other than needling (1.75mm-2mm) every 7-10 days. It definitely does cause something to happen as I can see some intermediate hair growing where there was none before. The only problem is that cosmetically theres not much of a difference. Hair volume is slightly increased, but not really enough to be noticeable to others who arent obsessed with hair haha. I'm just theorising here, but I think on its own microneedling probably isn't that effective, or if it is the results might take years to show themselves all the while the balding is taking its natural path, reducing the effectiveness. I have taken pictures and will show my 6 month results in June/early July. Next year I will add minoxidil. I really wanted to avoid it but I think it might do wonders for me if other people are anything to go by. I'm 36 and a diffuse thinner with NW1.5 hairline but weak density, so this should be effective (in theory).
