How to Maintain Your Blonde Hair Color like Anne Hathaway and Demi Lovato

Gregory Pace / BEI Images; FameFlynet Pictures; Josiah Kamau/BuzzFoto/FilmMagic; John Limparski/WireImageJust 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).
