The Gua Sha Hair and Scalp Brush promotes follicle health. This patented, travel-friendly brush doubles as a fascia and muscle massager. Gentle stimulation helps to boost and improve blood circulation in the scalp, maximizing follicle health. Works as a sensory, de-stressing scalp massage tool that also helps brush through hair strands. It can also soothe anxiety and migraines by stimulating cranial acupressure points.
