Don't Miss:

This weekend, Lauren Conrad Tweeted a picture of her new pink strands—and we got the inside scoop on how she created it! “We used chalk!” her colorist Kristin Ess told us exclusively. “It’s a super-fun way to temporarily color your ends because it washes right out. But it’s best when worn in a bun because it will get on your clothes.” Ess also told us that she and Conrad will be posting a full how-to on their site thebeautydepartment.com tomorrow. And this isn’t the first time Conrad tried color: she previously worked peach tips and blue highlights. (The latter look has been tried on over 100,000 times in our virtual Hollywood Makeover Tool since she got them in September!) Tell us: Do you like her new hue?

Oscar-winning actress and Lancôme ambassador Kate Winslet teamed-up with the cosmetic brand to create a special three-product line to benefit her new Golden Hat Foundation. After seeing an Icelandic documentary about autism, Winslet was moved to start the the charity to better the lives of children living with the disorder. (The hat concept was inspired by a poem written by a child who has autism.) “I walked away from the experience unable to let it go,” she told InStyle exclusively. But creating the charity was just a start. She’s also supporting it with her work. This April, Winslet will publish The Golden Hat: Talking Back to Autism ($20, amazon.com), a series of celebrity self-portraits and inspirational words. And this holiday season, she collaborated on Lancôme’s Golden Hat collection, which directly benefits the charity. “I took the idea to Lancôme and they said, ‘Let’s absolutely do it,’” Winslet said. “They’re very passionate about the charities they support.” Click “See the Photos” to check-out the gorgeous pieces and hear what Winslet loves about each one.
