A Hairy Discovery

After a while, I wonder what is in hair? Just strands? I have collected samples from my mom. I took both black and white hair because I thought that black and white hair are different (not just looks).

After, I saw that both of the hair’s bottom have a little lightbulb-like bottom, almost microscopic, but the white’s bottom is smaller than the black one.

    The light bulb is hair root; collection of cells that synthesize and build a single hair – not unlike a miniature 3D printer extruding a protein matrix!
