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).
Most reviewers on Ulta love the GHD Gold, praising how quickly it heats up, how it makes their hair feel, and how long this tool has lasted them. Some reviewers did feel that it was too expensive and didn't like the lack of control they had over the temperature setting. While those with very fine hair may find the 365-degree setting too hot, the lack of different settings, in this case, is to help prevent hair damage. The price is steeper than some, but it's also a straightener that's built to last, which helps justify the price.
Achieve straight, sleek locks: Mist hair with ghd heat protect spray and place a fine section of dry hair between the plates of your ghd Classic Styler. Ensure that the styler is as close to the root as possible before closing the plates. Then 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.
