Yeah that's true. It's all trial and error for most people in the end imo.
I'm quite hyped for Follica though.
What pen do you intend on buying when you start? dr pen or derminator? I have a dr.pen ultima a6 and i quite like it. cartridges are relatively cheap, right now i have sorta stopped needling my scalp, focusing on some forehead lines that i needled years ago that are starting to creep back lol
