Nicky Clarke has urged Britain's Duchess of Cambridge to "get rid of her grey hair".
The top stylist - who has beautified the locks of Princess Diana and the Duchess of York - thinks Princess Catherine needs to keep the colour of her intact because "until you're really old, you can't bee seen to have grey hairs".
Nicky said: "Kate needs to get rid of her grey hair - It's not a good look. She does have amazing things done to her hair and it can look great, but unfortunately it's the case for women - all women - That until you're really old, you can't be seen have grey hairs."
The hairdresser was referring to when the Duchess was spotted with grey hair while she was pregnant with, now 2-month-old daughter Princess Charlotte.
However, Nicky says it's a completely different story when it comes to men's hair and even "a few strands of grey would be a disaster" for her.
He told the Daily Mail: "It's different for men. Men can go grey in their mid-50s and still be considered attractive. It's the whole silver fox thing. But it's not the same for women. Kate is such a style icon that even a few strands of grey would be a disaster, so I highly recommend that she cover it up. I hate grey hair."
