It looks like Ms. Stone has gone back to her ginger roots.

The 24- year old actress swapped her blonde tresses for red shoulder length locks, debuting the look while spotted out and about with boyfriend and fellow Spiderman star, Andrew Garfield.

While many may think Emma is a natural ginger, but the convincing actress has many fooled. Stone is actually a natural blonde. It was only upon the suggestion of director Judd Apatow during the filming of Superbad, that the young starlet decided to go red.

The color definitely suits Stone. Whether blonde or a fiery redhead, the actress pulls of both hair hues beautifully, which is no easy feat. Wearing red isn't easy. Stylist to the stars, Jennifer J, also owner of Juan Juan Salons in Southern California says women with cool or pinkish skin rock red best. Guess this is what helps makes Stone such a stunner.

While finding your right red might be tough, the maintenance is also a challenge. Red fades super fast, so you'll want to wash hair sparingly and use cool water when you do. And avoid at home dye jobs when it comes to this shade. Red is a definite DIY don't.

So just how does Stone keep her hair so pristine? Turns out the star has a few go-to hair care products she simply swears by. Emma is a big fan of Davines. The family owned line creates products based on sustainable beauty.

Stone's favorite products in the line are Davines Love Smoothing Shampoo and the Nounou Conditioner. The actress just might be a closet beauty junkie herself. She may be a movie star, but she knows exactly what works for her skin and hair type.

"I need a lot of moisture for my skin, but not for my hair," said Emma. "I have the opposite problem with my scalp as I do my face. This clarifying shampoo doesn't weigh down my hair, and the conditioner is great for baby fine hair. It also smells very good, too," she explained.

Gotta love a gal who knows her beauty products. And we're loving the red on Emma just as much as we do the blonde.
