If you saw this guy's latest video update, you can see he's regrown quite a lot of hair. He used to be slick bald. Ao that's quite impressive. Apart from dermarolling, he also rinses his hair with apple cider vinega before. And, he uses topical DHT blockers. Saying that, I did my second dermastamping session yesterday. It was intense. I drew some blood. It hurt like a b**ch. I applied rosemary oil after 2 hours. So this is how I'll go about it, I reckon.
