This is for people who don’t like to mess around. They want their hair looking its finest, and they want it now! This high-quality, sleek Black Derma Roller has 540 x 0.3mm Titanium Needles. This is the very best. Our Derma Roller is most effective when used in conjunction with Regrow Shampoo, Conditioner and Tonic. By adding this simple extra step into your routine, you will be getting the most out of your Regrow Hair Products. Derma Rolling (also known as Micro needling) works a couple of ways, firstly, it assists Regrow Hair Tonic (aka The Magic) to penetrate the scalp deeper, getting right to the root of the follicles. Secondly, by breaking the epidermal layers it triggers skin to produce more collagen and blood flow. Both resulting in thicker, healthier, and shinier hair. Important Stuff Do not use if skin is infected, irritated, has dermatitis or if the skin is broken. Do not share the roller, this is an exclusive relationship. If skin becomes inflamed, discontinue using.
