The plates of the HSI Professional are made of solid ceramic that is infused with tourmaline. The combination allows for consistent temperature and gives hair a smooth finish. The wide range of heat settings, starting at 140 degrees Fahrenheit and going up to 450 degrees Fahrenheit, gives you more control over styling and makes this an ideal straightener for multiple hair types.
With a maximum temperature of 450° F, the BaByliss Pro Nano Titanium Straightening Iron can really pack a punch despite its otherwise small frame. One thing to note though: these heat settings are not pre-set like the CHI G2 hair straightener we also reviewed, and you will need to play around with them to find the right temperature for your hair. This shouldn’t be a problem if you have a Saturday afternoon or two to kill, but may not be ideal for users that are looking for a flat iron with pre-recorded settings.
The two strips of silicone atop Bio Ionic’s flat iron plates seem silly, but they serve an important purpose. By buffering the outer edge of the plates, they reduce your chances of hair snags. They also force you to glide the flat iron more slowly through your hair (they are called speed strips, after all). While the slower technique maximizes shininess and smoothness, the speed strips can become a bit of an obstacle if your hair is thick.
Achieve stunning curls: Mist hair with ghd heat protect spray. Section the hair and lightly mist with a curl hold spray. This will help give hold when creating each curl. Place a fine section of hair between the plates of your ghd Classic Styler vertically 1 inch away from the root. Gently close the styler with minimum tension. Turn the styler clockwise by 90 degrees; continue to turn the styler by another 90 degrees as you glide from root to end. For an intense curl, pull the styler very slowly away from the head in a continuous smooth movement. An s-shaped vertical curl is created. To complete the style, repeat through all sections. Finally, separate and brush out the curls with your fingers.
