After: Penny Chan

“We wanted to transform her style from ‘heavy hair’ to movable, swingy hair,” says Cutler. He cut her hair into a bob with a strong outline, then razored the ends to give it movement. Colorist Christy Marino applied a gloss, which camouflages any gray hairs and adds shine and richness. “I love it!” says Penny. “It’s so different than before—it looks more polished and it’s much easier to manage. I just apply gel, blow-dry, and then add hair spray. With my black hair, the grays were really noticeable, so I was happy to cover them up. It makes me feel younger!”

Best for: Straight or wavy hair; any face shape except oblong.

Styling tips: Give flat hair oomph by first spritzing on a voluminizer at the roots while hair is wet (try Cutler Volumizing Hair Spray, $20, amazon.com; or Bumble and Bumble Thickening Hairspray, $27, bumbleandbumble.com). Then apply a dab of shape-holding gel like Redken Velvet Gelatine 07 ($17, amazon.com) to the rest of hair before blow-drying. Says Heser, “I used a flat boar bristle, which creates less curl on the ends than a round brush. It’s a more modern way to style a bob than just curling it under.” Finish with a spritz of hair spray for hold and to prevent frizziness.
