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.
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!!
I own the GHD V Sapphire Styler and I am in love with it. It straightens through my medium to fine , puffy curly hair nicely reducing it to a sleek , straight and soft state. The box it comes in is really petty and you usually can purchase the iron as part of a set with another product such as a comb to styling spray, depending on where you get it from. It can be petty expensive but will last you the best part of a decade. The styler is create to curl, wave to straighten your hair and it heats up really fast and glides through your hair magically. However it makes it alittle bit trickier to curl/wave hair because it doesn't have much grip on your hair but usually the straighteners will gain alittle more grip the longer you use them (what I found with my iv styler).
Though it has no adjustable temperature setting but it automatically adjusts with your hair. You do not need to set the temperature. The ghd Classic 1 inch Styler iron never split ends and your hair would never look dry, frizzy and damaged. It gives you the shiner and silkier hair for its advanced ceramic heater skill. The ghd Classic 1 inch Styler iron takes a very short time to straighten your hair. Never pull out your hair.
Against the ghd IV Styler: Although the IV Styler is one of the original products in the ghd range, it’s still pretty beloved amongst customers, especially because of its affordable price. Unlike the new ghd Gold Professional Styler, though, this product only boasts one sensor that stretches across both plates, meaning it’s less intuitive at heating your hair.
