What it is:
Via Crystal Ion Dual-Bristle Vented Styler has a special bristle pattern, uses alternating rows of tufted and regular bristles. This makes the brush pick up and control hair like a round brush, smooth the hair like a boar brush and yet they provide the speed of blow drying of a vent brush with the largest vents of any brush in the market.
What it does:
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.
What else you need to know:
The ions atomize the water droplets making them small enough to penetrate and condition the hair.
