•balayage

•  

  From the French word for "to sweep," balayage is a technique where colorists hand-paint highlights directly onto the hair. "A lot of people think balayage is really chunky, but I paint it on finely at the root and thicker at the end—mimicking the way a child's hair looks,"

Ash Blonde

A hair color with an undertone that's a cooler-toned greenish-gray, as opposed to warm gold. "Some people have a natural dishwater-blond base that's ashy,"

Emma Roberts's Honey Blond

KEY COLOR NOTES What makes this blond so unique is the layers of dimensional color: A base of toffee blond is accented with ribbons of caramel and straw. I love this treatment for women who were towheads as children and are reticent to admit they're now light brunets. It also looks great on fair complected beauties with a pinkish hint in their skin; those with yellow notes can look too tone-on-tone

KEY COLOR NOTES If it's not natural, flame red hair can look costumey against nearly any complexion. But a coppery auburn with a wash of strawberry highlights like Stone's is flattering on skintones ranging from ultra-fair to tan and tawny. (Skip the shade if you're olive or darker.) And do take a tip from the star by asking that your brows be touched-up, too. The simple tweak enhances the overall sexiness of the shade.

WHO SHOULD TRY IT "I can't think of one woman who wouldn't look good in this cut,"  That being said, the look does require a bit of maintenance: Keeping the layers around the face trimmed to cheekbone level (not longer) is essential 

Katie Holmes's Barely There Layers

WHAT IT IS Extra-long, chest-length hair with subtle thinning at the ends to prevent the styling from looking Marcia Brady.
WHO SHOULD TRY IT Are you that girl with long, silky hair that that dries straight with very little effort? Meet your new hairstyle. "I would even recommend this look for someone with curly hair that relies on weekly blowouts. If you can commit to the styling, it's ultimately a very low effort cut

 a cross between a bob and a shag." The hair is cut above the shoulders, and then razored from back to front at a slight angle. "This is the kind of style that comes to life with the styling."
WHO SHOULD TRY IT "Minus the bangs, this would be a great short cut for someone with curly hair," . "The layered side pieces will keep the hair from forming that dreaded A-shape." Otherwise, this versatile cut would work for most face shapes and textures
