I had just shed to almost nothing on top when I commenced microneedling so needle depth was less relevant to getting the instrument ensnared in my hair. I also add Estrogel usually which helps provide a better environment in terms of being less sticky. I have been doing the entire scalp and face and neck for that matter for age reduction and scar reduction and hopefully longer anagen. But yes, I shed horribly when I added spironolactone, microneedling and rather rough massages and brushing all at once, more or less so it's always better to titrate treatments in general and dosages and maybe not massage but instead microneedling. I also get the masseter muscle botox treatment which someone somewhere claims improves baldness outcomes by 18 percent. It's on Rob's site which I have mostly memorized.
I can still see scar tissue on top but it is blending in better and better and it seems this scar tissue is becoming less cobblestoned and more productive. My theory related to brushing or hard wire brushing is that you can't brush yourself bald unless you yank out knots, meaning that the hair pulled by the microneedler is about to come out soon anyway. It helps to hold down the patch being done and do it in front of a mirror so you can more precisely located the areas of concern. Since microneedling cures scar tissue it seems not particularly relevant at what angle it enters the skin. If snagged, just gently calibrate the direction and reverse roll it and the hair will come free. Notice what sorts of hair you lose doing this and brushing and combing because it can inform you about how crappy most of it is likely to be. I have tons of corkscrew hairs coming out, along with whitish hairs that are similar but worse so I yank those on my own.
