Big: Tease.

Once associated with '80s mall rats, teased hair is now being reinvented in high, sometimes crazy, style.

We know it isn't very open-minded, but we tend to be a little hostile to trends that can also be found in the pages of our high-school yearbook. But, as with leggings, neon colors, and jelly shoes before it, the appearance of teased hair on the most stylish spring runways has persuaded us to reconsider. "We had been seeing so many simple, sleek, blown-out styles on the red carpet--and that's beautiful--but it was time for something new," says Guido, who created the looks on these pages and also teased models for the Marc Jacobs and Louis Vuitton runways. "This hair is about a rougher, matte texture, and using that to reinterpret classic shapes, like an updo or a ponytail, with more volume."

Although teasing might seem like a knotty hassle, it's actually simple to do and works well with any hair type (it's especially good if you have fine hair that normally won't hold a style). And according to the pros, as long as the style you're teasing into shape has some definite structure, it won't look grungy or over-the-top. "You can use it to make something rather understated," says Eugene Souleiman, who fashioned teased updos at Dolce & Gabbana. "You don't have to look like Barbarella or like you're in the B-52s."

Playing Rough

The right tools keep hair standing tall without looking shellacked.

HAIRBRUSH The pros use a flat, medium-size, natural-bristle brush, rather than a comb, to tease the hair. The boar bristles on Mason Pearson #B3 Handy Bristle Paddle Brush and Denman D82M Medium Size Grooming Brush produce a soft look and minimize damage. To untangle hair before bed, start at the ends and work gently toward the roots.
