The cut: The Modern Shag
Celebrity inspiration: Rosie Huntington-Whiteley
What it looks like: "The key to getting a shag cut that looks cool and modern is to keep the layers longer in proportion to the length (otherwise it looks dated)," said Rodney Cutler, a Redken ambassador and Cutler salon owner.
What to ask for at the salon: "If you have thick hair, ask for lots of layers so to take out some of the weight," he explained. "If you have fine, straight hair, make sure the layers are a bit choppy and not too seamless in order to achieve the desired texture."
Styling tip: "The new and improved shag cuts look best styled a bit more polished," he added. "Hair should be smooth and healthy looking; however, avoid blow-drying with a round brush — you'll end up looking more soccer mum than supermodel.
"Whether you're wearing it straight or wavy, make sure the ends are straight. Then finish with a texturising product.
