Break, need for a shoot or just want to change hair color, many are the stars to be passed by the blonde box Marilyn or brown Monica. And the least that can be said is that these (rather successful) changes have made them gain in sex appeal.

Let us remember Kristen Stewart's youthful blond. After playing the heroines in the Twilight saga, the least we can say is that the short asymmetrical cut, a rock'n'roll strand, and brown hair go like a glove.

In another genre, flash back on Jennifer Lopez's platinum blonde sweep. Although at the age of 46, the beautiful actress and singer of Puerto Rican origin has something to envy, let's admit that we prefer her brown hair with caramel reflections, a bit wiser and tidy.

During the shooting of the saga Hunger Games, Jennifer Lawrence trades her pretty blond hair platinum for an intense brown coloring. Dark brown hair that suits the character of Katniss Everdeen.

More spontaneous, the cut change and radical color of Kim Kardashian. Tired of her long brown hair, the heroine of the Incredible Kardashian Family, dared the short platinum blonde square. An unexpected change, but rather successful, however ephemeral, since it took little time to Kim, before readopting its brown color.
