Revlon’s One-Step Hair Dryer & Volumizer

Hair styling is a game of restraint. We regularly toe the delicate line between getting it just right and somehow falling into the over-styled category. Can you blame us? The gray area between the two is so tiny, you'll miss the "danger ahead" sign if you blink. We can think of many a bad hair day that began as these famous last words were uttered: Just one more

[insert: brush, curl, tease, or spray]

. Poof! You better grab that hair tie or wide brim because your strands just entered the no-go zone.

Finding a solution to over styling is no simple task—and we're not exactly calling this your end-all—but Revlon's One-Step Hair Dryer & Volumizer ($59.99) is just the ticket for cutting down on your risk of not leaving well enough alone. This nifty tool is one part round brush, one part curling iron, and one part blow dryer—a good hair day trifecta, if you ask us. It seems the faithful reviewers at Amazon agree, with one fan even calling it the "best hair tool ever invented."

Revlon promises the Volumizer will cut dry time in half by combining both the drying and styling processes into one. The trick is to start with damp (read: not wet) strands. Separate hair into small sections, then place the tool just under the roots and brush outward to the ends. You can even hold it on your roots for a few extra seconds to lock in more volume.

The scope of hair textures represented in the more than 2,700 reviews is impressive: Frizzy, flat, curly, thin, tightly coiled—just to name a few. The one thing that really put us over the edge in our desire to add this one tool wonder to our Prime basket was the before and after photos. We're suckers for a transformation, especially when it comes to hair. Anyone can promise a styling tool works wonders, but we're not going to write home to Mama about it until we see it work its magic on strands with lackluster oomph and relentless frizz just like ours. Check and check.
