Summer is a time for less fussy hair, and a loose updo is a great way to keep cool both literally and figureatively.

Jessica Alba has the look down. To mimick her style, try these steps.

Start with wet hair. If you have fine hair apply a spray gel like L’Oreal Professionnel Techni.art Texture Spray, or if you have thicker hair go with a mousse like Tigi Catwalk Strong Mousse. Use a diffuser on your hair dryer and rough dry, holding head upside down part of the time to get lift at your roots.

Once hair is dry, scrunch with a dime size amount of gel or mousse to get some texture and a piecey look.

Take the hair from your ears down and secure into a low, loose bun.

Divide the top portion of your hair into sections and tease a little bit under each section for lift. Then twist and loosely pin each section above and around the bun, keeping volume on top.

Finish with a hairspray like Tigi S Factor Vivacious Hairspray.
