Seeley adds: “The more soft rounded layers you have cut in, the more movement and bounce your hair will have. It’s all about keeping it soft and wispy, so weight is removed to create the shape. Remember, though, that layers can take a while to grow out, so you need to be committed to this style.”

What do you need to maintain the ‘cool girl waves’ style at home?

“To style this at home, I suggest lots of root lift,” suggests Irwin. “Try spraying something like Wella Professionals EIMI Root Shoot throughout the hair at 4cm intervals to give you volume throughout.

“Next, blowdry your hair and then tong horizontally, one section behind the tong, the next in front. And, to get that high-shine effect, consider using Sebastian Professional No Breaker – it’s a leave-in bonding spray that gives both strength and hydration – or the Wella Professionals Color Fresh Mask, which should add gloss and shine and a super luxury feel.”
