To achieve straight, sleek locks: Mist hair with GHD Heat Protect Spray (sold separately) and place a fine section of dry hair between the plates of your GHD Professional Styler. Ensure that the styler is as close to the root as possible before closing the plates. Gently move toward the tip of the section in one simple gliding motion. Repeat the process with each section of hair, gliding once from roots to ends.
It did get straight and it didn't pull or drag on my hair which was nice, but it took twice as long as it usually does (and lately i've been using a $35 flat iron I got from Amazon!) due to the fact that I had to go over and over it in increasingly smaller sections. I already use thin sections so this was just ridiculous. What annoyed me was that even after all this my hair remained poufy and never really got that shine I usually get. My hair btw, isn't even curly it's more wavy/frizzy/poufy--so I don't require tons of product or anything like that bc straightening my hair has always been an easy no-fuss affair. Usually, it takes like, one pass to get'er done.
Inferior hair straighteners take a very long time to heat, and you really need to make sure that they’re on their highest setting to have any effect. But that means getting lots of split ends, and you hair often looks frizzy, dry, and generally unhealthy. And once you go outside, if ever you live in an area that’s a bit humid the straight hair quickly goes to its default pouf settings. 
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!!
