If you’ve ever screenshotted a picture of a celebrity sporting blonde hair to take to the salon as inspiration, chances are that colour would’ve been done by Nicola Clarke. She’s indisputably the most famous of all the blonde colourists, and counts Kate Moss, Cate Blanchett, Kate Winslet, and Madonna as clients. It’s hard to think of a celebrity head she hasn’t touched. Every time Nicola has coloured my hair, she’s managed to walk that delicate line between what suits my lifestyle, and what I aspire to, so you’ll be in very safe hands with her (that’s if you can get an appointment).
