Ceramic and electrical straighteners were introduced later, allowing adjustment of heat settings and straightener size. A ceramic hair straightener brush was patented in 2013. Sharon Rabi released the first straightening brush in 2015 under the DAFNI brand name. The ceramic straightening brush has a larger surface area than a traditional flat iron.
The plates in this techy tool house an internal microchip that constantly measures and maintains an even temperature. With no random hot or cold spots, you'll get smoother, straighter, strands in fewer passes. (Spoiler alert: Fewer passes equal less damage). Adjustable temperature settings — from 260 to 410 degrees — make this ideal for any and every hair texture.
