beauty queen: rosie huntington-whiteley

how to skip the scorched tresses look this summer.

If your weekend was anything like ours, it involved time spent on the beach, by the pool, or in the sun (or, you know, all three). Which is awesome in the moment--and then you step into the shower and realize that your strands feel like straw, your color is getting a green-tint to it, and you can barely get a comb through there.

Which is why, just as in winter you start OD'ing on the leave-in conditioner and moisturizers, in the warm weather you've got to switch up your routine to protect tresses from the elements. If anyone is doing it right, it's Rosie Huntington-Whiteley; the model-actress arrived at the LAX airport this weekend with summer-strong hair. For one thing, she's got on a hat, which is one of the best ways to keep strands from getting scorched. But for her strong, shiny, perfectly blonde 'do, here's your post-sun prescription:

CLEAN IT: Davines Su Wash - $18.50
Not all shampoos are created equal when it comes to giving chlorine the boot--this one leaves your hair feeling silky smooth, plus it smells amazing.

BLONDE IT: John Frieda Sheer Blonde Highlight Activating Conditioner - $4.99
Skip the lemon--which will only lead to even brittler tresses--and go for a product that will both condition and enhance your blonde notes.

PROTECT IT: Color Extend Sun Solar Screen SPF 12
Before heading out all over again, spray your entire head with this leave-in product, whose SPF 12 while help protect against both UVA and UVB rays (and the color fading that comes with them).
