Greetings, my M8 came with cartridges of 16 needles, 36 needles and Nano.. How many needles to use and what speed? Also what is your protocol? I was thinking to use 1.5mm once per month and 0.5mm twice per week right before I apply minoxidil in the morning. Any suggestions are appreciated!
Which is the best needle and speed for Dr.Pen M8?
