Straightening irons, straighteners, or flat irons work by breaking down the positive hydrogen bonds found in the hair's cortex, which cause hair to open, bend and become curly. Once the bonds are broken, hair is prevented from holding its original, natural form, though the hydrogen bonds can re-form if exposed to moisture. Straightening irons use mainly ceramic material for their plates. Low-end straighteners use a single layer of ceramic coating on the plates, whereas high-end straighteners use multiple layers or even 100% ceramic material. Some straightening irons are fitted with an automatic shut off feature to prevent fire accidents.
4. The button placement is very similar to the Remington flat iron. When the iron is powered on, quickly press the power button 2 times and a small lock icon will appear on the digital indicator under the Fahrenheit symbol. When the lock icon is visible you cannot change the temp or turn it off by accidentally pressing the buttons. To unlock, quickly press the power button 2 times again and the lock icon will disappear.
The nano ceramic plates in this straightener deliver far-infrared heat, a gentler alternative in and of itself. As if that weren't enough, there's also a reservoir where you can pour in some of the (included) argan treatment and thermal protectant, creating a conditioning steam that will strengthen and safeguard strands while you straighten. Admittedly an extra step, sure, but one that's well worth it.
