While the metallic gold and pink tones spray-painted into hair at Tracy Reese's Fall 2011 collection may not mesh for the everyday, the reverse curls that cascaded down models' backs are the kind of workplace appropriate that transitions into cocktail-party playtime with ease.

"A lot of times, using a curling iron can give you flattened waves. The great thing about this technique is that it builds volume around the face as you go," lead TRESemmé stylist Jeanie Syfu tells StyleList.

Also known as the S-curl, the shape was created by Syfu with the help of a traditional barrel curling iron with clamp. Syfu first prepped strands with TRESemmé's 24 Hour Body Mousse to build volume at the crown.

Then holding a horizontally sectioned piece of hair, first wrap the strands upward and around, clamp closed, and curl. After releasing, go on to your next section just below, and work in the opposite direction -- wrapping strands downward and around, and clamping closed.

Repeat the alternating up and down directions with each section to literally createe an S shape to your hair. The final result? A Veronica Lake-like flow of voluminous waves.

You can also add some texture and volume to your waves by hitting the roots with dry shampoo, followed by styling creme for hold. "The dry shampoo plus styling creme has been the pairing of the season, everyone is doing it. The dry powder absorbs oils and lifts the roots for volume, but the styling creme keeps things looking glossy," says Syfu.

And while we love the versatility of this style, the best part is that it's über-forgiving if you skip a day or two of washing; the low-maintenance waves only look more sensual with some dirt at the root.

Because as we all know, every woman likes to get a bit dirty sometimes.
