However, hair stylist Jo Hansford claims Kate’s hair is “too long” and needs to be cut.
Ms Hansford is a celebrity hair colourist who has been looking after Queen Camilla’s famous coiffured hair for 35 years.
The 71-year-old, who trained under the legendary Vidal Sassoon, shared her honest thoughts on the Princess of Wales’ hair.
She said: “She’s got lovely hair but I think it is too long.

“She’s so slim, and with hair you have to look at the whole image, the proportions, so I would take it up six inches.”
However, Ms Hansford said she was not alluding to the idea of “mum cuts”.
She continued: “I don’t agree with that idea at all.
“But as you get older you need a bit of shaping, because your face muscles start to drop, so bringing it all up to, say, shoulder length, can give you a lift. That said, everyone ages differently.”
She added: “Nothing dramatic happens to a woman’s hair on the day she becomes Queen.”
King Charles III and Queen Consort Camilla will be crowned at the Coronation on May 6.
Queen Camilla is expected to wear a dress designed by her friend Bruce Oldfield who was also the favourite designer of the late Princess Diana.
It’s understood that King Charles will be wearing his military uniform for the occasion; a more modern choice compared to previous coronations.
