The "Lob" (aka long bob) is the latest trend to take Hollywood, with stars of every age seen experimenting with this versatile cut.

A few favorites—

Heidi Klum: Slicked-Back
The key to Heidi's formal 'do is a sleek, lacquered finish. To get this look, try a long-lasting, strong hold hair gel— like Bumble and bumble Gellac— on wet hair.

Anne Hathaway: Romantic Waves
Loose, luminous curls work with any look, and add a softness to this (layer-less) cut. To keep your locks looking polished, finish with a lightweight shine serum like Shu Uemura Silk Oil.

Camilla Belle: Au Natural
Messy, bed-head tresses are a sexy (and easy) way to wear the "Lob." To amplify your natural texture, try Fekkai Coiff Oceanique Tousled Wave Spray.

Gwyneth Paltrow: Sleek & Straight
A classic, this smooth style can easily take you from day to night. Be sure to use a high-quality flat iron— like the T3 SinglePass Duality— when creating this look, to protect your tresses from heat and styling damage.
