Seal Your Ends With a Large-Barrel Curling Iron
To make the ends of your hair as bouncy and frizz-free as they looked on day one of your blowout, Toth suggests using a curling wand. "If your ends are prone to frizz, then try gliding a large-barrel curling iron on them to seal them up all the way. It doesn't need to be anything fancy or with shape. Just let the heat of the iron work its magic and add softness and a slip to your ends." We love the T3 Bodywaver ($130, originally $160) for this.
