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.
We don’t know too many people that are using their hair straighteners vertically, but there must be a few since ISA has made a point of clarifying that this model is intended only to be used horizontally, i.e., perpendicular to your hair. According to the manufacturer, using the hair straightener horizontally reduces hair pulling for a more comfortable experience. This may be particularly important to you if your hair tends to knot easily or you have unruly curls and texture.
Hair breakage is an all too common problem, and even the most seasoned of hair stylists can slip up from time to time. That’s why LumaBella’s Keratin Duel Touch Hair Straightener features a unique smart heat sensor. This nifty little gadget can actually tell when there is too much heat for your hair, and will automatically adjust to a safer styling temperature!

T3’s white and rose gold flat iron seems too pretty to reliably function, but hey, sometimes miracles happen. There are four temperature settings ranging from 260 to 410 degrees, and the tool heats up in about a minute. Its ceramic plates are infused with tourmaline, a mineral said to make hair extra smooth because it emits negatively-charged ions. There’s no scientific evidence to support this, but my unscientific bathroom study found that this flat iron does indeed make my hair look shinier.
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.
