Hetepheres II was an Egyptian princess who was a daughter of the Old Kingdom Pharaoh Khufu (the guy who commissioned the Great Pyramid at Giza). There is a bizarre legend claiming that Khufu forced her into prostitution in order to raise funds for the pyramid’s construction, but this is considered very unlikely by most Egyptologists.
In one tomb painting, Hetepheres II is portrayed as having short yellow-colored hair. Certain white supremacists like to use this image as proof of a “Nordic” ancient Egypt, but there are actually various cultures across Africa wherein people may dye their hair red or blond. In fact, it appears to have been even trendier among the Kushites to the south of Egypt than the Egyptians themselves. So no, I think Hetepheres was aiming for a Beyonce look rather than being a natural blonde.
