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.
I purchased this ghd after a hairdresser friend used hers on my hair. I couldn't believe how well it worked so I purchased the same model. I have curly frizzy hair and this straightener actually makes my hair shiny and even holds my hair straight if my hair gets wet in the rain. I use a hair straightening treatment on my hair before I use the ghd as you should with any straightener and this keeps my hair from becoming brittle. I have lovely comments about my hair since using it. It feels very soft and is healthy. I can adjust the heat setting so it does not get too hot. It is very quick to heat up and beeps when it is ready unlike others I have tried .It is so simple and quick to use. Because it is the wider ghd I can do my hair in less than five minutes. I have long hair past my shoulders. Very happy with this one.
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.
