I have very thick, long hair that tends to frizz in bad weather. I have tried many hair straightners, but I have to say, these are by far the best. They are packaged beautifully and look amazing. So on trend. They have ceramic plates, which I am led to believe, are much kinder to hair than metal versions, and the LED temperature control is ideal. There's even a temperature lock which means that you are in control at all times. I find that they take the frizz away brilliantly and leave me with smooth, shiny hair. These are 2 in 1 though, and they also curl and I find that the curl doesn't drop as quickly as with other straighteners. It's just so handy to have the option to curl or straighten. It makes hair styling fun. What's so great about these also, is that there is a 30 minute shut off timer. No more panic about if I've left them on. I love them.
