Human hair contains trace amounts of minerals like calcium and iron, which are essential for bodily functions and come from the food we consume.
Fascinatingly, the origins of these elements can be traced back to ancient star explosions, specifically supernovae.
In the distant past, massive stars produced heavy elements like calcium and iron through nuclear fusion. When these stars exploded, they scattered these elements across the universe.
Over billions of years, this cosmic material became part of the dust and gas clouds that formed our solar system, the Earth, and ultimately, all living organisms.
So, while it may sound poetic, it's scientifically true that the atoms in our hair—and our entire body—were formed in the hearts of ancient stars, making us literally made of star stuff.
