Older: Adams's acting is above reproach. Her stuffy, shellacked chignon is not.
Younger: This braided and middle-parted updo is a great argument for revisiting your Pippi Longstocking days. Just remember: Twisted up into a bun, braids look chic; worn down, they really only belong on the playground.
Older: This is pageant hair, and pageant hair is aging. (Unless you're in a Miss Octogenarian contest.)
Younger: To get Beyoncé's loose, carefree (and young-looking) waves, rake a tangerine-size dollop of light-hold mousse from roots to ends. Let hair air-dry, then wrap sections of various sizes—so it doesn't look too done—around a medium-barrel curling iron for five seconds each. Finish by running your fingers through it to break up any stubbornly perfect curls.
Older: If these droopy curls can suck the life out of the preternaturally cool Moss, imagine what they would do to a mere mortal.
Younger: Moss—and pretty much everyone else—looks cooler and younger with roughed-up hair. Take a cue from the supermodel and pair rumpled hair with smoky eyes and a stylish outfit to make sure the look is rock and roll, not just-rolled-out-of-bed.
Older: Barrel curls and a forehead flip make Banks's hair look so stiff and sculpted you could easily imagine it on a bust in a museum.
Younger: A middle part and tousled waves are youthful and the perfect texture for her shoulder-length lob.
Older: Don't get us wrong, dark brown can be rich, lively, and beautiful. But single color tends to look flat and a little wiglike.
Younger: The lighter and darker shades of creamy blonde create dimension and make Barrymore's skin glow. (OK, the fact that she was pregnant in this picture probably helped a little, too.)
Older: This baby-chicken-on-your-head color wouldn't work on anyone, and it makes both Suvari's hair and face look brittle.
Younger: An ashier blonde with ever-so-subtle roots has her looking her age.
Older: Hough's too-perfect bob with ends that curve under says small-town news anchor.
Younger: But one with beachy texture and a messy part says cool girl, possibly even cool surfer girl. We know which one we want to look like.
Older: The words "old" and "pixie" shouldn't go together, but in the case of Lawrence's shaggy, overgrown look, they do.
Younger: What a difference a trim makes. To keep a pixie gamine, get regular trims—or wear those bangs swept back.
Older: With pouf that goes from the hairline to the crown, this complicated twist puts the "old" in "old Hollywood."
Younger: Sure, her hair is lighter, but Johansson's loose, slightly roughed-up style would look youthful no matter what the color. After you've pulled hair back, run your hands over the surface from back to front to free those flyaways.
Older: With that deep side part and perfectly twisted side swoop, Blanchett's style looks a little mother-of-the-bride.
Younger: This is basically the exact same hair, minus the shiny perfection. It really is as simple as that.
