Great hair never goes out of style. Just take a look at these leading men of the ’40s, ’50s, ’60s and ’70s and their modern-day doppelgängers. Believe it or not, says Regis Artistic Director Terry Varty, all eight superstars have essentially the same timeless cut: “Three to four inches long on the top, shorter on the sides and a little grown-out looking. It’s a versatile cut that works with a lot of different hair textures.” From there, it’s all in how you style it.

The Rebel

Brad Pitt wears it like James Dean

Work a dime-sized bit of Regis DESIGNLINE Whipped Wax into damp hair (skip the comb; your fingers will do the trick) to get this gravity-defying pompadour. Then, apply a few shakes of American Crew Classic Boost Powder to add more lift at the roots. Aim for a smooth, matte-looking result, Varty says.

The Prepster

Matt Damon wears it like Robert Redford

Work a golf ball-sized glob of Redken Guts 10 Volume Spray Foam through damp hair. (Don’t try to fight your natural part.) Feeling Redford’s retro vibe? Grab a blow-dryer to get a natural finish. Digging Damon’s piece-y, more modern take? Let hair air-dry.

The Gent

Colin Firth wears it like John Wayn

This stately style best suits wavy and curly hair, Varty says. To emulate tough-guy Wayne’s high-shine wet look, apply a dime-sized amount of Regis DESIGNLINE Finishing Wax Gloss Polish to towel-dried hair. Not as brave? Sebastian Craft Clay Remoldable Matte Texturizer provides Firth’s subtler finish.

The Charmer

Ed Westwick wears it like Cary Grant

Crib the game of these dashing dudes by working a quarter-sized amount of Regis DESIGNLINE Soft Sculpting Glaze into wet hair. Comb into place, with a part on the side, and let hair air-dry. “You can wear it more conservatively during the day like Grant, and then relaxed at night like Ed,” Varty says.
