Via Crystal Ion Thermal Round

The world's finest thermal round brush. Designed to last for professional use. The thermal core is riveted to the handle to extend the life of the brush. These are the original Ion generating brushes. They incorporate tourmaline resins in the bristling which causes the brush to generate negative ions when it is brushes through the hair. The ions atomize the water droplets making them small enough to penetrate and condition the hair. The ions also help to restore the damaged cuticle of the hair so it can retain the moisture, making your hair healthier every time you brush!
