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.
Featuring advanced ceramic heat technology, the ghd Gold Professional Performance 2" Styler is designed to operate at the optimum 365°F styling temperature for healthy-looking hair with enhanced, lustrous shine. Styling thicker, longer hair is quicker and easier thanks to the larger plates that glide through strands without snagging for fast, effortless styling and flawlessly polished strands. It heats up in as little as 30 seconds to tame frizz and transform coarse textures into sleek, smooth styles that last. The styler has contoured, round edges to unleash undulating waves, and with its styling versatility, you can change your look every day.
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.
