I discovered a thing called dermarolling.
And apparently, among it's many benefits is hair growth. Which is not the way people generally use one of these rollers. Since it seems to be more of a wrinkle remover type of thingy, but anyways, I'm going to try it on my head.
This is going be a little out of order, because by the time you are reading this... I will have already tried it.
It seemed easy enough, just roll these on your head, so I bought a set and used it in conjunction with my other stuff.
My first thoughts, rolling needles on your scalp hurts! In most spots it is not that bad, but you will come to certain spots where it just jabs you in the gut. Not unbearable pain, but you will definitely feel it..
Using Dermarolling To Trigger New Hair Growth
I found that instead of rolling, using it as a meat pounder works way better. Just imagine angrily pounding those hairs back into your infuriatingly sparse follicles. That is what the dermaroller do. Tapping it on your head hurts way less than rolling and you can probably get in there deeper too.
But the most important thing is to not get crazy with it. I don't know how deep is deep enough or how long you should be dermarolling for maximum efficiency, so I just went with whatever was comfortable for me. Videos in the YouTuber-sphere from various "experts" and actual experts, were not definitive. But it seemed like there is a perfect midpoint between barely scratching the surface and hurting yourself. As for how long I do it, maybe a couple minutes just enough to cover all my bald spots. There are people who suggest doing it for 20 minutes or more. So the answer here is also unclear, but I don't think spending that long stabbing holes into your skin is good for it. Heck, I am not sure if even stabbing it for a couple minutes is good either, but I am willing to experiment and see.
Overall, it is best to just ease into it and slowly experiment. Take care, be safe, and keep your roller sanitized!
