Buying quality hair styling supplies can sometimes feel a little painful in the pocketbook. Good flat irons, hair dryers, and curling irons can cost more than $100. That's why we love the idea of Amika's three-in-one curling iron. The tool features interchangeable barrels in three-quarter-inch, one-inch, and one-and-a-quarter-inch diameters (along with a heat-proof glove, since the barrels don't have clips to hold the hair in place), which makes the $175 price tag a little less painful—especially when you shake your head full of gorgeous beachy waves!
