For curling, place a section of hair between the plates closest to the scalp, clamp the plates, and turn styler through 180 degrees while holding the end of the strand. Pull styler through the hair slowly, always maintaining the 180 degree turn--it helps to slightly tip the nose of the styler downward, careful not to let the hair fall out. It also helps to pull the strand forward when trying to curl hair at the back of the head.
_{Dual-Zone Technology: You will have heard of Tri-Zone Technology if you own a ghd Platinum Styler, so think of Dual-Zone Technology as its little sister. Instead of three heated regions, this styler features two, one towards the tip of the styler and another closer to the base. This essentially means the straightener has better control over the way it heats your hair, instead of over-delivering in one area and lacking in another. Think quicker styling and a more uniform look in terms of sleekness and smoothness.}
My previous GHD has lasted me 8 good years with no issues (I loved it!). Recently the wires on the chord have become exposed so my partner decided to replace it for my birthday. He went to hairhouse warehouse and the staff persuaded him to purchase a Halo instead after rubbishing the GHD. I used the Halo once and whilst I quite liked it, the outer plates were too hot to touch, which makes it difficult to style my hair (I use two hands and twist for a wave effect). I went back to the store to change over to a GHD. The staff member warned me that the quality of GHDs is poor after changing manufacturers about 4 years ago. I wasn't worried though as I thought she was pushing Halo for incentive reasons. I used the GHD for the second time this week and when I plugged it in it made a pop sound like the fuse had blown - it shortcut the circuit in most the house. I then plugged it into a working socket and put the tongs to my fringe - it melted/burnt my hair immediately after being on there for a split second. There is literally melted hair all over the plate tongs and I can't get rid of the smell of burnt hair. To say I'm disappointed is an understatement.
Giving you ultimate control of your hair, ghd’s range of brushes innovatively style hair without causing static, helping to create the optimum silky smooth blow-dry. The ghd Ceramic Brush features a ceramic barrel to retain heat too, making sure your blow-dry is super speedy and the natural bristles on the Natural Bristle Radial Brush work to create a smoother finish, adding volume to mid-length hair.
"About to re-purchase!My GHD has lasted going on 9 years (literally through THICK & THIN).* Nice firm/gliding grip/No tug/pull of the hair. Opens and closes gracefully (doesn't sound like it needs WD40 LOL. EASILLY CLEANS. NO Lines are left on the hair strand , easy for clients to use with confidance as well. Doesn't project a burning steam with product close to scalp. Bevels well. Works great as a waver..... this is a Universal Flat Iron for all ethnicities!"
GHD used to be amazing however now the products are cheaply made. I have had many over the years and now done with them. Every single one of my straighteners just stopped working one day. (conveniently just after the warranty). Unfortunately won't be re-purchasing a GHD unless quality changes. Customer Service also not the same, no longer interested in helping.
This is an expensive straightener, but it's worth every penny! I've had mine now for over a year, and I know I'll have it for many years to come. The iron itself is black and gold. I have long, thick, straight hair, but it gets a little wavy underneath if I let it air dry. If I blow dry it, it gets a little poofy and I use this to give it a more smooth, sleek look. It takes a couple passes of going over my hair before it's completely straight, but with cheaper ones it takes longer. It doesn't take too long to do all of my hair. It heats up super fast, and if I'm in a hurry and forget to turn it off, it turns off by itself after thirty minutes. I have dropped it a few times, and it's still going strong. I recommend this for everyone.
To have straight hair, you just mist your hair with the GHD thermal protector. You then start at the part of the hair that’s closest to the roots, and then you glide the GHD Classic 1-inch Styler to the tips in one smooth stroke. You can also follow the easy directions for soft movement and for curls, which involve some turning while you glide from root to end. 
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.

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 ;-)

Bought these on recommendation of my hairdresser to deal with my chemo damaged hair. Thankfully I didn't lose my hair but it did go really thin during treatment. 18 months on from treatment my once fine, straight and easily managed hair has come back in thick with random curly and wavy bits. My old straighteners which had served me well over the years were snagging, pulling and breaking both the damaged and newly growing hair but these ones glide through the hair with hardly any breakage.

^{GHD Classic Styler, from the name itself, you can deduce that this simple yet versatile device was made to style and straighten. Armed with a rounded barrel and advanced ceramic heaters, you can curl, flip, tease, wave, and straighten any hair type and texture easily without damaging your hair’s external surface. The infra-red heat technology infused within the plates also releases more negative ions than other products so your hair’s natural oils and luster are retained despite repeated exposure to maximum heat.}
