I try to needle as rarely as possible, because my skin is still visibly red 3 days afterwards. That's why I decided to needle no more than twice a month. So up to now I did 1,5mm every two weeks. However, I don't know if that is effective enough as there is no study backing that particular protocol, while the 2mm every two weeks is backed by the Chinese study. I haven't yet decided, but I guess I will give the 2mm a try (even though I already had a slight improvement with 1,5mm). But yes, thats why I'm really looking forward to Follica finding out, what the best needle length and frequency is
Yeah i know the frequency for wounding for wrinkles etc is every month, but the jury seems to still be out about the frequency for hair loss. Im just going to keep it at 2.5mm every week and see what happens, nothing to lose really.
