Tek Ceramik 13mm-42mm Antibacteric Round Brush. The Professional CERAMIK The Original thermal-roll brushes are the result of an innovative technique: ceramic is applied to the roll using a high-tech process called "coating". The bristles are made of a material resistant to high temperatures. 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.
