    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 an amazing straightening iron! It truly only requires one pass and it glides so smoothly across my hair. The only downside is that it doesn't have auto shut-off.

      Doesn’t seem to be as hot as my old one. Still does the job.

      I was hesitant about buying this product because I have previously purchased a Bio Ionic gold pro straightener (not from Overstock but from another site) and it stopped working after 3 months. This purchase actually blew me away! The plates are much smoother than the gold pro and my hair looks incredible! It looks shinier and healthier, which is unheard of when it comes to straightening hair. Overstock offered it at an amazing price and I am so happy I am able to own this product. I highly recommend it!!

      This is the best straight iron on the market! (And I'm a licensed cosmetologist and have tried many different brands).

      Took me a bit to get used to just doing “one pass”. I have used multiple brands in the past and alway did pass after pass and it was just out of habit. After using this for months now, I tried a regular Chi and really hated it. Very happy with this purchase.

    • 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.
