Thanks for the info. The pen has a dial with .25 increments. I suppose you could estimate between since it's a smooth dial and not segmented. I have hair everywhere else and was just thinking of trying the corners where I have the most loss. I just have no idea what 1400-1800 per cm2 would even look like
no idea what it looks like but i just go till my head feels on fire with my slower derminator lol . Your ment to go 2 cm into healthy hair but im not sure how you define healthy so do the whole thing into the donor zone 2cm hence the 30mins.
I was thinking of buying the new a6s model but it went out of stock never came back assume due to global pandemic
