Last week Grazia Daily reported that Kate Middleton’s locks have been trumped in the hair do stakes by none other than Andy Murray’s avid courtside supporter and girlfriend, Miss ‘full-mane’ Sears.

Not the types to take a battle of the tresses lightly, we took a trip down to our local House of Charles Worthington Salon to see what all the fuss was about. “It's quite normal for our clients to come in with a picture of a celebrity that they would like to emulate when havign their hair restyled, but last week we noticed a significant shift from women asking for Kate Middleton curls to the looser, more casual Kim Sears waves,” explained stylist supreme Sophie Clare Clare. Wow - Apparently being royalty isn’t even enough to stick it out in the blow dry leagues nowadays. 

The secret behind Kim’s luscious locks? It’s natural thickness, apparently. Put simply, Andy Murray’s babe has a full-head of healthy looking hair that Wimbledon watchers are just gagging to achieve. “Women like to create something they don’t have,” says Sophie. “While Kate has a very ‘done’ look with bouncy curls, Kim’s hair is much more natural and even looks like it could have been slept on. Women feel this daytime look is more attainable and attractive.”

1. Blow dry with a big bristle brush

Want to know how to work Kim's undone chic? Of course you do. According to Sophie, who tackled the hair of gorge Grazia Beauty Intern Chiara, the secret is in the brush. Brandishing the biggest barrel brush in the Charles Worthington tool kit, she explained that this particular blowout relies on the bounce that the big bristles create.

2. Curl with a curling iron

With locks about 70% dry – the magic percentage used by all Charles Worthington stylists – Sophie roughly curled sections of Chiara’s hair, before sealing it with a shot of cold air. Where K-Middy's hair stylist would use a smaller brush to form those perfectly rounded, cutesy curls in the lengths of the Duchess' hair, the Sears look requires body or a natural ‘bend’, as Sophie calls it. And while Chiara’s waves drop once released from the momentous brush, the point of a ‘Kim’ is to look groomed but undone. 

3. Add volume by back brushing

'With a soft smoothing brush, gently back brush at the root to create a little more height on the crown area as well as extra movement,' says Sophie.

4. Add a spritz of oomph

Of course, there’s a magic ingredient in the creation of this  look. Charles Worthington’s Full Volume Shampoo and Conditioner, £5.19 adds buckets of extra oompf, but it’s the Front Row Volume Blow Dry Spray, £6.29 that truly transports your mane from lifeless locks to full-on Sears sheen.

5. Hold in place with spray

But what about the casual-yet-perfect face-framing fronds at the front of Kim’s hair? "It is most probable that this is the natural consequence of her tucking the lock behind her ear," confirms our stylist. Fret not though, dear Sears fans. For those of us who have hair unwilling to co-operate, it's perfectly possible to tonge the front of your tresses into a natural looking bend. And the cheat’s guide to keeping those unruly strands in place? Charles Worthington’s Shine Maximum Hold Spray, £5.19. Hair mousse is like SO Kate Middleton, don't cha know?
