Clémence Poésy's long and lustrous mane first caught our attention in Harry Potter and the Goblet of Fire and we've been tracking it at every Chanel front row (and in her Gossip Girl eps) ever since. And now we can reveal her secret. It seems Clémence, like us, believes in the power of a pharmacy beauty brand as she relies on Klorane Camomile Extract Shampoo ($9.95) to gradually produce highlights and enhance shine. The gentle shampoo is free from synthetic dyes and is Clémence's choice "to keep the colour fresh." Follow up with Klorane Camomile Extract Conditioner ($9.95) and you're on your way to emulating Clémence's cool and chic vibe.
