The Breo S3 Scalp Massaging Brush uses soft silicone tips and vibration to stimulate blood circulation at the follicle level — the proven first step to reducing shedding. Paired with Kerasilk's Redensifying Scalp Serum, a clinical formula that progressively restores hair thickness from the root, this duo delivers a complete two-step approach to thinning hair.
