How Julianne Hough Balances Beauty and Fitness

PS: Do you have any surprising tricks for keeping your blond hair vibrant?

JH: So here’s the lowdown. If you’re blond, your hair tends to get a little brassy, so you can use a purple shampoo to revive your hue. But sometimes if you leave it in too long, your hair can turn slightly gray. In order to get that brassy color out, you can rinse your hair with some dish soap, and it'll cancel out that ashy hue. It’s not something I recommended doing often or in place of your shampoo, but it definitely helps in an emergency.
