I've been researching into dermarollers and there seems to be differing opinions on them. I'm looking for a way to improve absorption of minoxidil because I can't always apply it twice a day and it seems like a dermaroller could assist me with this.
What is the correct size to get? I have short-medium length hair.
How often should you use it?
