FHI Heat Stylist Les Haverty Forecasts 3 Head-Turning Styles for Spring/Summer 2007.

Inspired by the couture catwalk and the red carpet, this year's warm-weather hair trends are all about formal structure slightly unraveled and giving way at the seams. This process of order falling into disarray is innately sexier than random chaos, according to LES HAVERTY, Artistic Director and Stylist for FHI Heat, a manufacturer of ceramic tourmaline styling irons, curling irons and blow dryers. "We see this trend traveling through spring into summer, because there is an underlying sophistication in the message," he says.

These looks, like the shoulder-length flounce of deconstructed waves, the disheveled chignon, or "half-up, half-down" 'do, suggest self-control yielding to the forces of nature, like a once-tidy English garden rampantly overgrown. These looks are pulled-together enough for the office, yet alluring enough for after-hours.

Haverty identifies 3 key trends as spring-summer musts for women:

1. OLD HOLLYWOOD, DECONSTRUCTED. "This is the story of fallen elegance and lived-in glamour," says Haverty. Shoulder-length hair with a diagonal fringe is coaxed into a side-parted look with a retro '40s feel without the crisp finish of old-school, gelled finger waves. Haverty cites Jennifer Garner's tousled, bohemian chic curls created with FHI's Curling iron at the 2007 Golden Globes.

2. THE BUN, UNDONE. "The updo has always been a classic for graduations, proms, and weddings," says Haverty. To keep it contemporary, he advises not setting the bun too low or too high, and knowing how little or how much hair to sweep back. "The bun's newest position is at the occipital crest at the mid-back of the head. Higher up looks too prim and proper, and too low on the nape looks dated." He advises not pulling the bun too tight, but leaving it slightly messy or undone.

3. THE STRAIGHT AND NARROW. "This look is here to stay," he says. The super-long, glassy-smooth look, flaunted by Gwyneth Paltrow and Nicole Kidman at the 2007 Academy Awards, has become a truly iconic style in Hollywood. "When an actress has grown her hair really long, using high-heat tools to create that sleek pin-straight drop is the best way to show it off." For the 2007 Oscars, Paltrow's hair was straightened with FHI's Runway iron, while Kidman, Beyonce and Queen Latifah's tresses were smoothed with FHI's Platform iron.
