For curling, place a section of hair between the plates closest to the scalp, clamp the plates, and turn styler through 180 degrees while holding the end of the strand. Pull styler through the hair slowly, always maintaining the 180 degree turn--it helps to slightly tip the nose of the styler downward, careful not to let the hair fall out. It also helps to pull the strand forward when trying to curl hair at the back of the head.
As mentioned earlier, the GHD classic Styler uses ceramic plates which heat up faster than other materials but it doesn’t emit negative ions like tourmaline flat irons, which doesn’t only straighten hairs smoothly but also makes dry and damaged hairs healthy by counteracting with positive ions. So, in terms of professional use and/or greatest results, GHD classic styler can’t be recommended. That is my personal opinion as an author. As an alternative, I can recommend you to read CHI Air hair iron review, it is tourmaline ceramic, and thus little more in price in comparison to classic styler.
This overpriced iron is good if you have naturally fine, soft or wavy hair. If you have coarse, thick hair it will not do the job, or it will take you several passes. This is not unique to the GHD, this applies to ALL CERAMIC straighteners. The Auto shut off and dual voltage is awesome, but it is not worth it if the iron does not provide sleek, durable straight hair. If you have kinky, unruly, poofy hair go with TItanium, hand down!!
