This boar bristle brush helps to smooth hair and distribute natural oils from the scalp for added shine. Designed with longer rounded bristles to reach farther into hair for a smoother finish. Perfect for blow-dry and stretched-out styles and to detangle long, thick hair. DIRECTIONS Brush hair from root to tip. Repeat for extra smooth results. Use with the Cantu Smoothing Leave-In Conditioning Lotion or the Thermal Shield Heat Protectant if using heat.
