My Spyronolactone cream will arrive any time soon, and I'm thinking about starting needling my scalp. What would be the best needle length for it? I want to get closer to my follicles, but not enough for the cream to go systemic. I remember reading somewhere that 0.5 mm was the best.
What do you think? Also, what routine do you recommend?
