What it is: An attachment that targets uneven or thinning edges, a widening part line and loss in hair density from age, post-partum changes or damage from overstyling.What it does: It helps create vertical exfoliation micro-channels to safely reawaken the scalp creating the optimal environment for your hair to grow stronger, thicker and shinier. Imperceptible micro-channels deliver key hair care ingredients to your scalp and follicles for maximum performance and results. It also protects your hair follicles by firming the upper layers of the scalp that naturally thin with age, giving hair strands a thicker foundation and helping to reduce hair loss. Scalp stimulation instantly improves micro-circulation to naturally encourage hair follicular activity. Helps any thinning areas appear less noticeable as a result of reduced breakage and premature fallout. How to use: Use GloPRO® SCALP on clean, product-free hair. Hair may be damp or dry. Part hair into sections, lightly hold hair taut and in parallel with hair strands, gently glide GloPRO® back and forth over the scalp for about 5 seconds per target area. Continue parting hair and using GloPRO® until all desired areas have been treated. Attachment only; device is sold separately
