Human hair contains trace minerals like calcium, iron, magnesium, and zinc, which are essential for its growth and structure. These minerals, present in minute quantities, originate from a cosmic process tied to ancient star explosions, known as supernovae.

Stars, during their lifecycle, fuse lighter elements like hydrogen and helium into heavier ones, including carbon, oxygen, and the aforementioned minerals. When massive stars exhaust their fuel, they collapse and explode in a supernova, dispersing these elements into space.

Over billions of years, these ejected materials mix with interstellar gas and dust, forming new stars and planets. Our solar system, including Earth, formed from such enriched cosmic clouds about 4.6 billion years ago. The minerals in Earth’s crust, water, and living organisms—including humans—trace back to these stellar events.

Calcium strengthens hair’s keratin structure, while iron supports follicle health. These elements enter our bodies through food and water, ultimately incorporating into hair.

Thus, the trace minerals in every strand connect us to the universe’s ancient history, reflecting the remnants of stars that exploded long before our planet existed, a testament to our cosmic origins.
