In short YES! You absolutely can use too much heat on your hair. Burning hair is not a good smell, it’s not a good look either! You may end up having to get a pretty severe haircut if you’re not careful about the amount of heat you put directly on your locks. Read through this to get an idea of what’s safe and what will leave you wishing for a good trim (or possibly a wig).
Good Hair Day, commonly known as ghd, is a manufacturer of hair care products based in Leeds, United Kingdom.[1][2] ghd leads the market for hair straightening irons and is sold in over 50,000 salons worldwide.[3][4] The company was the first hair tool sponsor of the Victoria's Secret Fashion Show, and is endorsed by celebrities including Victoria Beckham, Madonna, Gwyneth Paltrow, and Jennifer Aniston.[5][6]

Over a decade on from revolutionising hairstyling with the launch of its first styler, ghd remains true to its founding ethos: the spirit of transformation. Ghd have since broadened their super range from stylers to professional quality brushes and the most impressive hairdryers available on the market today. Even after all these years the Ghd hair straightener is still very much a must have for most women and men who want smooth, sleek luscious hair - especially with us girls from Millies. 
Due in large part to the damage we inflicted on our poor locks during this time, we’ve learned that heat protection isn’t just a luxury: it’s mandatory when it comes to hair straightening. That’s why so many hair straighteners now feature conditioners built right into the plates. We also learned that excess heat can cause permanent damage to hair, so now many flat irons come with automatic turn-off features or self-adjusting heat settings. Well, as the saying goes, there is no progress without a bit of struggle and our hair certainly struggled during the early 2000’s!
Since 2004, ghd has raised approximately £2.5 million for the Breakthrough Breast Cancer charity.[28] The company produces a limited edition pink hair iron every year, with £10 of the sale price being donated in support the charity.[29] In 2010, ghd partnered with charity "Mom It Forward" and SafeHouse Denver, a women’s shelter that serves victims of domestic violence and their children, in an event at Sephora.[30]
The more temperature control options you have, the more control you'll have over the heat you'll be applying to your hair. Keep in mind, any type of heat styling can be damaging to your strands, so you want to take care not to use too much high heat, especially if you're styling daily. Flat irons that have lower temperature options that start around 250 degrees Fahrenheit are ideal for those with thin, damage-prone hair. If you do have thick hair, higher heat settings can help straighten those curls. To help prevent damage, you should start with lower heat first, and then only increase as needed. Keep in mind, anything above 400 degrees has the potential to damage your hair. Even those with coarse, curly hair should stay within the 350-400 degree range to be safe.
EDITOR’S CHOICE: CHI has and always will be a powerhouse brand in the hair straightener industry, and the company’s new G2 Ceramic and Titanium Flat Iron is no exception! Packed with ceramic and titanium technology, this hair straightener was designed to give you silky, shiny styles without snags. We also love its easy-to-read, color-coded temperature settings, so you know the temperatures that you are using at any given time!
Go ahead, roll your eyes (we did, too, at first), but this iron is no joke. It's not just better than expected; it's so effective that we keep going back to it again and again. It allows you to select the temperature setting based on your hair type (fine, medium, or coarse) and smooths down every last flyaway. And, we're not gonna lie, we love the rose-gold plates as much as we love this iron's hair-softening effects.
Whether you have particularly curly hair or thick locks, this T3 hair straightener is designed to leave you with a shiny finish in a fraction of the time of other hair straighteners on the market today. Specifically, the T3’s smart SinglePass technology maintains consistent heat throughout the entire plate to straighten all hair types with one glide.
Just want to clarify some things I read in the reviews. I purchased this from Amazon.com as the seller, not a 3rd party seller for just over $100, almost $100 cheaper than Sephora and Ulta. The hair dryer was 100% authentic with a hologram code, and I was able to register it without problem on the GHD website in case anything happens and it breaks within the 12 month warranty. Amazon only has a 30 day return policy, so be sure you register your hair dryer. I bought this to replace a different brand hair dryer that broke and I had not registered it. The other company could not do anything for me since I did not have proof of purchase anymore. This hair dryer is awesome. It’s sleek and dries my hair fast, and I love the cold shot button that helps set my blow out. Solid product that I hope will last for several years.
GHD’s “styler” is permanently set to 365 degrees Fahrenheit, which the company says is the highest temperature hair can tolerate before it becomes damaged. As a person who went from a dark brunette to blonde highlights, I can vouch for its straightening power on processed hair. And though I don’t typically think of “comfort” as a flat iron necessity, the springy hinge that connects the two plates really did make it easier to clamp and glide the tool down my hair with minimal effort.

I can't believe Amazon would allow one of their trusted sellers to sell fakes. I received mine today and it took about 5 seconds to realize that it was fake. I could not register it on the ghd website, and I came across the information below to help identify fakes. This straightener did not have a reset button on the plug, and had many more of the 'give-aways' that it was a fake! DO NOT BUY FROM THIS SELLER.
