Contains 100% natural, active ingredients like Biotin and Arginine that have been scientifically proven to grow facial hairs where none or very few hairs were before. Together with The Beard Roller, The Activator Serum creates the best micro-environment to reactivate beard growth. It does so by activating the dormant hair follicles that lie in a resting state underneath the skin. The Beard Roller penetrates the top layer of the skin, which activates new hair follicles and makes it easier for The Activator Serum to get absorbed, and helps stimulate beard growth. In order to give yourself the absolute best conditions for growing a beard, we recommend using The Beard Growth Kit as it contains everything you’ll need to activate your beard growth - including The Activator beard growth serum.
