Matrix Haircare, part of the L’Oréal Professional Products Division, has announced Made in Chelsea star Stephanie Pratt as its Matrix celebrity blonde ambassador.

Pratt, who appears in a new campaign #LAtoLondon for its So Color Beauty Extra Blonde UL-AV shade, commented 'I was meant to be born a blonde - it matches my personality. London undone is my go-to style and I've maintained a fresh bright blonde by using Matrix Total Results Hello Blondie Shampoo and Conditioner every day and Matrix Total Results So Silver each week in between appointments. Blondes definitely have more fun!'.
