Kate Middleton debuted new blonde hair during a visit the new Natural History Museum gardens, and the look wasn't exactly received warmly by the internet.

To the point where Kate seemingly switched things up for her next public appearance a few days later, showing off a significantly darker color.

And it looks like Princess Diana's hairstylist, Sam McKnight, was not here for people speculating about Kate's look, writing in a statement, "I am shocked, horrified, dismayed, and disgusted by all the nasty comments about the Princess of Wales today. A woman’s hair is very personal to her. It’s armor, defence, confidence and so much more."

He continued, "I cannot believe how evil and lacking in any kind of empathy are the comments, the majority made apparently by other women, attacking a vulnerable other young woman, who has no choice, by dint of who she married and the role she took on, to bravely face the public. I’m sure she would rather be away from the public arena. She has brilliantly and quietly, unselfishly represented our country, the soft power we still have as a nation."

He concluded his message with, "Cancer affects individuals differently, but is life-changing for everyone. So FFS LEAVE HER ALONE. SHAME ON YOU."

As for whether or not Kate was wearing a wig / extensions, source close to Kate denied both possibilities to the Daily Beast.
