Think Pink! Lauren Conrad Debuts "Cotton Candy" Hair

Hills alum and reality star shows off newly dyed tresses on Twitter

Daring new 'do or shocking new hue? You be the judge of Lauren Conrad's pink tresses!

The 25-year-old tweeted a link to an Instagram photo of her "cotton candy bun" on Saturday. The picture shows streaks of pale pink mixed in with her trademark blonde locks and piled atop her head.

This isn't the first time L.C.'s rocked rainbow hair…

In July, the Hills alum dyed the ends of her hair different hues of pink and blue. Why that color combo? Her fans voted for it!

 "Roses are red, violets are blue," she tweeted . "The color of my hair is up to you!"

In October, she shared a photo of her "peach tips" on the social media site.

Way to keep it colorful, girl!
