Kate Middleton’s gray hair recent triggered discussions about the age of the Duchess of Cambridge.

On the online forum site Quora, one person asked why Middleton has gone gray when she isn’t that old after seeing a photo of the mom of three with some gray strands above her head.

Sophie Oldfield, a resident of the United Kingdom, said that the phrase “gone all gray” is not appropriate because Middleton hasn’t gone all gray. The royal fan uploaded several photos of the Prince William’s wife to prove that her hair is not all gray.

“She is a brunette with a few grey hairs. Obviously, the public is more bothered than she is… If she was so bothered, she could easily get it dyed by the best hairdressers… Do people really not have anything better to do that zoom in on her parting!” she wrote.

Amanda Lindsay, a research administrator, said that a person doesn’t need to be old to have gray hair. Joseph Bangura Lee seconded Lindsay’s thoughts and said that Middleton is not that old yet.

“She’s not one enough to prove her appearance to be an old lady. To millions of people, she’s still young… She’s not yet a grandmother… If you’re going to meet her and you see that parts of her hair are grey, you can keep to it but don’t bother to tell her that she has grey hair,” he wrote.

Margaret Smith, a retired woman, said that Middleton’s gray hair may have more to do with genetics than her actual age. Em Fairhall, a writer, also said that the only evidence of gray hair on Middleton is on the base of her roots and it’s a very small amount, which means she hasn’t gone all gray.

Shelley Kesselman, a former student at Episcopal Divinity School, said that brunettes tend to show gray hair more compared to blondes and this could be why Middleton’s gray hairs are visible at times.
