Platinum blonde hair is chic all year long, but it's especially hot for summertime. But, just like any color treated hair, it requires some maintenance to prevent brassiness and yellowing.

For a true, silvery-gray or bright white platinum, try these tricks.

TONER

A great platinum starts at the salon. Your stylist should have the products and tools to accomplish the color you want, but if you need to tone out yellow between visits, try a salon quality toner with an ash or violet base to counter any brassiness.

After washing your hair, towel dry and apply the toner, starting at the roots and working through to the ends with fingers or a comb. Let it sit for 15 - 20 minutes and wash out. (Note: It's normal for the product to oxidize and turn a grey or purple color on your head. This just means it's working. The longer you leave the product on, the more it will tone to a bright white or grayish color.)

PURPLE SHAMPOO

Purple counteracts yellow, so use a deep purple shampoo, like this one by Paul Mitchell, every time you wash your hair. Massage it in, let it set for a few minutes, then rinse.

HAIR MASQUE

Since platinum color is most often achieved by bleaching, you'll probably need to pamper your hair more often. A good hair masque or deep conditioning treatment should help restore moisture and prevent additional breakage. Try applying the product to damp hair once a week, let it sit for up to 15 minutes, then rinse.

DRY SHAMPOO

Color treated hair will maintain more vibrancy if you wash it less often (I'm talking a twice-a-week maximum, if you can stand it.) Between washes, use a dry shampoo that's formulated with a hint of light color, like Batsite Light Blonde.
