Going platinum tends to make hair brittle and dry, which is why it's best suited for those of us with short haircuts, like Michelle Williams' chic pixie.

Icy blonde is an attention-getting shade on its own, and it's also the perfect canvas for experimenting with other colors. "Since the hair is already light, a pop of color is fun," says Nicole Leal, master stylist at West Hollywood's Nine Zero One Salon. Make like Zosia Mamet and add just a kiss of color -- in this case, blush pink -- at the roots of your platinum bob.

You don't need to have white-blonde hair to play with pink; rose gold hair is one of the hottest hair colors of the moment (see: Kylie Jenner). The trend has inspired a variety of interpretations, from classic strawberry blonde to cotton-candy pink and everything in between.

The fair-haired can achieve a natural rose gold with an in-salon or DIY toner. "Put a strawberry blonde wash over your golden blonde," says Janelle Chaplin, stylist and global creative director for O&M. "This will look stunning for fall."

You can get the look at home with a pink or red toning conditioner. "Try a sheer conditioning mask to create an all-over blush tone," Nawrot says. "Modify your timing to five minutes for soft color, or 10 to 15 minutes for bold color."
