Katy Perry's Perfect Blowout

"It's important to start this style with a solid foundation, and that begins with washing the hair," says Jen. I like [this] shampoo and conditioner because they support any style by nourishing the scalp and hair without weighing it down.

"After washing, blow dry with a round brush for fullness. I am loving the new Harry Josh Pro Tools Blow Dryer because it gets hair full and smooth, and it is super lightweight."

"Once dry, set a deep side part and curl large sections of the hair under with a medium-sized curling iron," says Jen.

Loosen the curls by brushing the hair out with a boar and nylon bristle hair brush. "Tuck the parted side behind your ear and secure with bobby pins, if needed," she adds.

"Finish with a light veil of hair spray," says Jen.
