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.
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.
I love my ghd hair straightener and use it several times per week. It heats up quite quickly (in the region of 20-30 seconds) and heats to the perfect temperature for my hair. It's nice and light and feels comfortable to use. I find it less damaging to my hair than other cheaper straighteners, but find that it's definitely worth investing in some argan oil or other heat-protective product. Ghd straighteners are on the expensive end, but I think it's worth spending the extra money to buy a product that does a good job.
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.
