Tek Ceramik Antibateric Oxy Round Brushes 13mm-42mm. The strong CERAMIK Antibacteric Oxy brushes are the first real antibacterial brushes thanks to bristles that are made of a material to which a powerful antibacterial agent has been added. The roll is treated with an oxygen anodizing process that makes the brush easy to clean. Why choose CERAMIK? It is Antistatic. It distributes the heat evenly without causing thermal shock to the hair. The porosity of the ceramic makes the hair shiny. It closes the scales of the hair by fixing the cosmetic dye. The professional bristles are resistant and make of Stylon 66. The 100% FSC Certified natural wood handle is ergonomic and non-slip.
