Exfoliation & Dandruff Removal: The soft, dense teeth gently lift away dead skin cells and product buildup (like sulfates and parabens) from the scalp. Improved Product Absorption: Use the brush with shampoos or gels to enhance their effectiveness, ensuring better cleansing and deeper penetration of hair care products. For Better Absorption: Apply essential oils or other skin products to the skin and use the massage brush to work them in for better absorption.
