The perfect brush for long hair and updos. A great oval brush that looks fantastic in any setting.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!
