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 is my second GHD flat iron. I had the first one for around 5 years. Any flat iron that lasts more than 1-2 years already gets points from me. I broke the cord on the old one but I liked that iron better than the ones I have used in the past (Chi), so I got a new GHD and went a step up from the classic styler to the this time. I can't remember what website I ordered it from but it was on sale. It was still expensive but knowing that my last one lasted for years it's cheaper than me buying a cheaper iron and needing to replace it yearly. It takes about 30 seconds to heat up, it does not have different temperature settings. When it's ready it makes noise, it startled me the first time because I wasn't expecting it lol. It sounds like a cell phone ring tone. Now I like it bc I know when it's ready to use. It comes with a little black silicone (I think) cover that slips over the plates so you can put that on and put it away while it's still hot, or if you're packing, throw it in your suitcase as soon as you're done using it. I have long, naturally thick frizzy curl, that I bleach, blow dry, basically put through torture! The humidity where I live has been AWFUL lately. There are days that I flat iron my hair and it looks great and smooth and I walk outside and it explodes. Unfortunately I think that until I find a miracle product or go back to getting keratin treatments, that's just the reality of my hair and the humidity. I dont think any flat iron will be able to miraculously lock out all humidity. I get my hair shinier and smoother with my GHD iron than with other irons I have used. Now, if I can learn how to master flat iron curls!
As far as we’re concerned, this is the best hair straightener we’ve tried. Not only does it heat up in record time (only 30 seconds until it hits 365°F), it’s also been lauded for its frizz fighting capabilities—as mentioned above, a must down South. What’s more, it lasts. One editor’s trusty Classic Styler is still going strong after 4 years of almost daily use.  
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!!
