Lily Collins has been announced as an ambassador for American haircare brand Living Proof, and will star in the brand's new campaign, which celebrates its 'mission of science in action'.

The Emily in Paris star commented 'When you treat your hair well, you’re treating yourself well. Living Proof’s philosophy is rooted in cutting edge science. Their products aren’t about masking your hair problems, they formulate them so your hair can be its best, most natural self. As someone who is always striving to keep my hair healthy, I was so drawn to this philosophy and the products that delivered the best hair I've ever had in my life'.
