Rsession Root Control ($180)
What it is: A heated comb that you pull through curly or textured hair to straighten and smooth it.
How it works: The ceramic rod heats up to 430 degrees; the "straightening combs" on each side of the rod detangle.
Why I loved it: You can lay the comb directly on your roots (a normal flatiron has a protective rim around the hot plates prohibiting that).
Insider tip: Point the comb tines down if you want to smooth the hair, up if you want more lift (be sure to hold the ends of your hair taut as you move the tool through).
