Centrix Technique Boar Brushes stimulate the scalp's natural emollients. The dramatic staggering of the bristling prevents broken hair, split ends and frizz by smoothing the hair cuticle. Thermal barrels on the Centrix Technique Boar Bristle Hair Brush allow for even heat distribution, and antimicrobial protection prohibits the growth of bacteria. Hair sectioning pick conveniently stores in the base of the grip.
