    A true break-through in straightening technology, this iron helps you straighten your hair in half the time. BioCeramic heaters heat up OnePass to 400 Degrees Fahrenheit with instant recovery for smooth results, roots to ends. OnePass Iron plates emit natural negative ions and far infrared energy that break down water clusters on the hair surface into smaller molecules that penetrate deeper, hydrating hair, removing frizzies, and creating healthy-looking, shiny hair.

      This is by far the best flat iron i have ever purchased. It is truly a one pass iron and it does the job. Got it as a birthday gift for my daughter, and she has frizzy hair. This iron worked miracles!!! Looooove it!

      This flat iron is a gift for my daughter. This is the one that is used at salon and it works great. Decreases time needed to flat iron your hair and protects from burning. Highly recommend.

    • Great Little Straightener
      Verified Purchase

      I've had my Bio Ionic straightener for over a year now. I love it...this Christmas I am purchasing 2 more for my daughters! They use mine all the time so I am getting them their own! It runs smoothly through my hair pulling, no breaking. I do wish it had an automatic shut off, because I have forgotten and left it on a few times all day.

    • Q:

      "How can I be sure this is authentic? Thank you for any help."

      • A:

        Not sure what to tell you. My hairdresser raved about one and I loved how my hair looked. But he told me to buy the one made in USA. After I received this, I looked at the box. It says 'Box made in China. Iron made in Korea.' Oh, well. This is still a great straightener and a great price. I like it. For me it was a good purchase.
