Introducing the Scalp Activation Roller+, the newest micro-needling tool that is designed to be gentle, yet effective in encouraging fuller appearing hair. This hand-held micro-needling tool is designed to gradually incorporate into your hair care routine to support the Bio-Pilixin® Activation Serum. We have developed the Scalp Activation Roller+ because regular micro-needling has been shown to have a positive effect on hair health in scientific literature. It features 540 titanium needles and is perfect for those looking to improve scalp health and encourage fuller hair by stimulating the scalp.
