Perhaps not how the first inventor of a hair straightener intended, flat irons have been increasingly popular as hair-curling tools. (Here’s how to curl hair with a flat iron if you want a refresher.) Haircare mainstay CHI caught on and created the Tourmaline Ceramic 3-in-1 Hairstyling Iron, which not only has flat inner ceramic plating but curved plating around the outer barrel. Not only does the rounded plating maximize the curling potential each time you wrap your hair, it also limits the amount of hair-snagging and clamp lines that often come with using flat irons to curl your hair.
Gisele uses this flatiron. Need we say more? OK, maybe a little bit: From the same hairstylist whose blow-dryer launch nearly broke the Internet, this green-plated flatiron is equally as buzzworthy. It has plates that are larger than most other irons (meaning fewer passes) and rounded edges that prevent snagging or pulling. And because it shuts off automatically after an hour, it's ideal for those of us who constantly forget to unplug our flatiron before running out the door. What are the best hair straighteners?

Of course since these are undertones, they are much harder to detect than the general color of your skin. You (usually) can’t simply look at yourself and just know that you have a medium skin tone with red undertones or a deep skin tone with yellow undertones. So how do you figure out what your undertones are? There are some sneaky clues hidden on your body and in your fashion choices to help out. Here are five of them.
