Don't Miss:

Just when we thought auburn was the must-have hue this season, celebrities like Anne Hathaway, Drew Barrymore, Reese Witherspoon, and Demi Lovato changed the game by unveiling sunny blonde makeovers. After a brief stint as a brunette, Witherspoon returned to her famous golden highlights, joining Barrymore, Hathaway, and Lovato in the trend. If you’re considering doing the same, be sure to load up on the deep conditioner afterwards to minimize damage. Brassy tones are the sworn enemy of blonde hair, so to prevent any shifts in shade, incorporate a blue or purple-tinted shampoo and conditioner into your routine. The cool pigments neutralize unexpected orange or yellow shades, and keep your highlights going strong until your next salon appointment. Our favorites are Clairol’s Shimmer Lights ($9; sallybeauty.com), Sachajuan’s Silver Shampoo ($28; sephora.com), and Rita Hazan’s Foaming Color Gloss ($26; ritahazan.com).

Drew Barrymore loves switching up her hair color, but somehow, it never looks dry or damaged. Her secret? Making drastic changes slowly. Over the course of a few months, the star has been gradually lightening her deep brunette to the sunny blonde she revealed while out in Hollywood yesterday. “I changed my hair color three times in the past year!” the star told InStyle in February. “Why not try new things? Life is short. I’ll always play.” That’s the spirit, Drew! Going from dark brown to a light blonde like Barrymore’s can be damaging, so if you’re also feeling playful with your color, follow the star’s lead and work in stages. “Try taking the process with days or even weeks in between to see if your hair will get too dry or damaged,” said colorist Marie Robinson, who works with Michelle Williams. “Start with a color close to your natural that is a subtle enhancement. If you notice excessive dryness, then work with the lightness you already have.” Because blonde hues tend to make the hair shaft more porous, aftercare is important. Invest in a color-preserving shampoo and conditioner duo, and apply an intensive hair mask once a week to lock in hydration.
