Derma Roller

This little tool is a little tricky to use on my scalp as I have long hair. I part my hair in different sections and roll back and forth once then move on to the next section. The first time I used it, it gave me a mild headache afterwards. It also makes my scalp feel very itchy for about 30 minutes or so after using. I've only been using it once a week and with the Growth Bomb shampoo, conditioner, serum and vitamins. All up, my hair is looking very voluminous and healthy so I'll keep going but I do find this a little uncomfortable to use.
