If you want to keep your colour from looking too try-hard, sun-kissed ends work well. 'Dipping the ends with a light colour gives a cool, lived-in edge,' says Strahan. Try Daniel Hersheson Micro Uplifting Treatment, from £65, or paint ends with Clairol Nice 'n Easy in Natural Ultra Lightm £6.99.
After seasons of ladylike updos, it seems topknots are now the pinnacle of sexiness, giving a rebellious look. 'This is a dangerous party-girl 'do', says Leighton. Strahan says, 'Wash hair with Herbal Essences Dazzling Shine Shampoo and Conditioner, £1.99 each, then twist small sections and pin to the head until you get to the nape of your neck.'
'I advise everyone to flirt with their eyes,' says Leighton. 'People will approach you more and you'll feel more confident.' To get this smoky look, paint Bobbi Brown Long-Wear Gel Eyeliner in Black Ink, £15, across the eyelids, winging the colour out at the edges. Smudge Lancome Crayon Kohl Noir, £15, on the bottom lashes. Finish with jet-black mascara like Dior Diorshow Mascara, £21.50.
PLAITED BUN'I'm anti-glam when it comes to wearing my hair up - I like it a bit undone with lots of flyaways,' says Leighton. Strahan says, 'Rake back hair with your fingers and secure the pony on the crown. Then plait the tail, wind it around the base, secure with pins and leave the ends visible.'
TUCKED UPMimicking a bob with long hair gives a different silhouette, accentuates the jawline and gives extra body,' says celebrity stylist for Herbal Essences Charles Baker Strahan. To get this wild texture, first prep with Sebastian Microweb Fiber, £14.10. Strahan tossled the hair from side to side, ruffling up the lengths, then threw a jacket over Leighton's shoulders and hair.
DISCO POUT'When I put on lipstick, I don't need much else,' says Hollywood actress and Herbel Essences spokesmodel Leighton Meester. Use Dior rouge Dior Haute Couleur Lipstick in Blazing Red, £22, then top with glitter for Studio 54 drama.
