Sharp, razored layers lend a dose of downtown cool to Sandra's look. Though edgy, razoring isn't easy on hair—it leaves ends susceptible to frizz and breakage, which only worsens with dry fall weather. Counteract damage with a nourishing gloss, which keeps hair silky and healthy.

Julianne's hair is simple and classic, but not at all boring. Her straight style gets a boost thanks to the layers at the ends. The result: an effortless, piece-y look. To emulate this look at home, coat your ends with a texturizing spray, then gently scrunch.

This isn't just any old updo. Instead, a disheveled bun with face-framing layers gives this style a romantic, windswept vibe—and makes it easy to recreate at home. Dab some pomade on your hair before raking it back with your fingers (no combs necessary!). The extra sheen adds polish to piece-y strands.

Sofia elevates the classic ponytail with a few tricks: a subtle center part, short layers and teasing at the crown. Overworked textures will look excessive, though—meaning that healthy, gleaming strands are integral to this style. Add a small dollop of light, flexible wax to flat-ironed hair (unless yours is naturally straight) to keep it silky and soft.

Christie's big, bouncy curls and deep side part have a retro vibe that echoes this year's fall runway looks. Hot rollers are the tried-and-true way to get this style, but don't settle for the set you used back in the 80s—newer models have a shorter heating time and ceramic rollers, which minimize heat damage to hair.

Unpleasantly sticky on hot summer days—but perfect for autumn—thick blunt-cut bangs make a stylish statement. Let them take center stage, as Jada does here, with a slick ponytail. The look is all about sleekness and shine, so banish any risk of frizz with a hydrating hair mask before blowing-drying and smoothing with a flatiron.

Reinvent the ballerina bun to beat the lingering heat of an Indian summer. With slight teasing and a few loose strands, Claire Danes keeps it modern and perfectly imperfect. Smooth fly-aways and rest assured that your 'do will last throughout the day with a glossing cream.
