How to keep your color balanced
Blond hair should be like a string quartet: smooth, multitonal, and devoid of brassiness. To avoid the dreaded yellow-orange shade that can creep into blond hair, use a for-blondes-only shampoo and conditioner designed to add shine and correct too-warm tones. Cunningham recommends Redken Blonde Glam shampoo and conditioner to her clients like Cameron Diaz and Drew Barrymore. (Also, check out our cheap, easy tips for platinum blondes.)
Look sun-kissed (minus the sun)
To look like you've spent a weekend at a beach house, just add highlights. "This is a great way to play with your hair and brighten your look," Cunningham explains. "You can add a few highlights around your face frame to enhance your face or add a lot of highlights to really pump up your overall look."
Ombré: still going strong
If you're a low-maintenance beauty, consider getting ombré highlights. This technique leaves hair darker toward the roots, gradually going lighter on the bottom. "It works for literally everyone, no matter what your base color or hair length," she says. It’ll give your color that brightness and energy it’s been missing." Cunningham pioneered the trend on model Lily Aldridge, and has since helped develop the Illumination technique used globally in Redken salons. Want to go the DIY route?
