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'm absolutely in love with my GHD.I will never buy another brand again. It heats up super quick, glides through the hair like silk and takes alot less time as with previous straightners i've had to go over the same strand a few times and it left my hair frizzy/flyaway and meant i had to use products to smooth it down! I dont really need to use any products except hot iron spray or cream protectant and a tiny amount of serum afterwards. The GHD also curls my hair perfectly, now that ive mastered the technique ;-)
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.
