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!!
To achieve stunning curls: Mist hair with GHD Heat Protect Spray (sold separately). Section the hair and lightly mist with a Curl Hold Spray (sold separately) to add shine and hold when styling. Place a fine section of hair between the plates of your GHD Professional Styler vertically one inch away from the root. Gently close the styler with minimum tension. Turn the styler clockwise by 90 degrees. For an intense stunning curl, continue to turn the styler by another 90 degrees as you glide from root to end; pull the styler very slowly away from the head in a continuous smooth movement. For a softer curl, pull the styler quickly through the hair away from the head in one 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 for more extreme curls, or with a wide-tooth comb for soft, loose waves.
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.
For me, the first and still very best of all ceramic stylers [and my dad is a hairdresser too]. It heats up fast, cools down relatively fast, works wonderfully and lasts a long time. In 11 years, I've bought two such stylers. The first one eventually died after 6 years of daily use, rarely skipping a day, while my second one is still going strong. I have no reason to recommend any other styler but this one. My hair is long and very fine.
