Nothing to brag about from my end. If I did have, I'd point you in the direction of the needler I've been using, unfortunately I could just be on to a crap needler. Who bloody knows. It's a 75mm one anyway.
This fad's died down since home follica trials and the dermabrasion train have shown considerable promise.
I had high hopes for needling but haven't reaped any rewards from all the sowing in my scalp I've been doing. I think the topical ingredients you apply afterwards will prove as important as the process itself. As I don't have access to these 'ingredients', I've found myself in somewhat of a pickle.
I'd love to hear some power stories of powerness from fellow needlers. C'arn you mighty masochistic narcissists.
