Dyson Airwrap Styler
The most common risk of styling one's hair is the heat damage caused by too-hot tools. That's why the Dyson Airwrap Styler ($549) is such a worthwhile investment. A single base comes with a dryer, various barrels to create curls and waves, and three different brushes. Better still, the heat control measures air temperature more than 40 times per second, so you'll avoid the overheated temperatures that damage strands in the long term.
