Brooklyn Decker's Must Haves: From Birkenstock Clogs to Electrolyte Drink Mixes

For a low-maintenance morning routine, Decker loves using this Roz Hair Oil ($45) to start her day (and hairstyle) off on the right foot. "I just don't have the bandwidth to really do my hair and put on a lot of makeup, so I try to get the essentials, which are typically things that take care of my skin, body, and hair," Decker says. "I started just adding in this oil, and it totally changed the texture of my hair."

Pro Tip: To get the most out of the product, Decker recommends applying the oil to the ends of your hair, and she also loves using a little more of the formula when her hair is wet so it soaks in and dries shinier. "Typically, I'll do two bumps [of the hair oil] in my hands, put 'em on my ends, and any leftovers, I'm putting on my arms, shoulders, and anywhere that needs a little extra love."
