I've only used this a few times at a friends but all I can say is that it is the best styler around. I've used to to curl and straighten hair. Each time I've straightened my hair and slept my hair has maintained its sleekness. When curling, the styler is incredible at obtaining an all day and night curl.
Honestly, one of the best styler's you can get.
This is the best hair straightener I've ever owned and I've had quite a few. I bought this about 4 months ago and now I'm kicking myself for spending money on all of the other ones I had before this. My hair is fine but tends to get either frizzy or build up a lot of static depending on the day and it also has a tendency to flip up at the ends. This styler helps with all of that. For the first time, my hair stays straight and smooth for the whole day without any flipping or frizz even towards the end of the day. It doesn't damage my hair like other stylers have and my hair just generally looks and feels a lot healthier.
If you're in the market for a new straightener, this one is worth the money.
Tips: There are a lot of fake GHD stylers on the market so be careful when you are making your purchase. GHD has a website checker where you can check to see if the site you are buying from is legit or not.
