Aside from ionic and infrared technologies the Bio Ionic Onepass Straightening Iron has something that is entirely new to me: silicon covered plates. They get the hair more in order when you’re straightening, save you a lot of time and reduce the amount of heat that you need. This one is great for African American hair, but I already selected the xtava Pro Satin for that because it’s more affordable.
So far I like this straightener. I haven't figured out the curling part of it but will be watching some videos next for that. Other than that it does a good job of straightening hair. I have super thick hair with natural ringlets. It usually takes multiple passes to get my hair soft and smooth. This one does a good job b/c it closes properly down on the hair and doesn't leave my hair looking crimped. The hair also doesn't get caught under the blades and rip out of my head like my last straightener. I haven't used the $200 one that is comparable with this one but I am super picky and this is a good straightener!!
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.
