Derma Roller - is a tool initially made for collagen production in the skin to cure wrinkles, scars, stretch marks and various skin irregularities. Research, later on, found out that when you roll the roller on your head or beard it causes hair and beard growth. How do you ask? Well, The small needles of the beard roller puncture the skin, the body recognizes this damage and begins the healing process by sending keratin and collagen, which are components that makeup hair. So it's sending hair to the areas you use the derma roller over.
I love it omg
It restored some bald spots I had after I cut my hair low. As long as you use it with the right oil you’ll see results.
Use it for collagen and skin restoration. Perfect for my sensitive skin and I’ve also used it to grow my edges.
