Colored Cuticle Dead Hair Keratin Shaft Strand
EDITORS COMMENTS
This print from Science Photo Library offers a mesmerizing glimpse into the intricate world of human hair. Captured using a scanning electron microscope (SEM), this coloured image showcases the remarkable structure and composition of a single strand of hair. Against a striking black background, the vibrant colours highlight the various components that make up our hair. The outer layer, known as the cuticle, is composed of overlapping scales that act as a shield to protect the central cortex. This cortex forms the bulk of each hair strand and is made up of fibrous protein called keratin. As we marvel at this image, it becomes evident that hairs are not simply lifeless fibers but rather complex structures formed by dead tissues. Beyond its aesthetic appeal, this photograph serves as an invaluable tool for biology enthusiasts and anatomical researchers alike. It provides insights into the biological makeup and anatomy of human hair while demonstrating how SEM technology can unlock hidden details in even seemingly mundane subjects. Science Photo Library has once again captured nature's beauty through their lens, reminding us that there is much more to discover within ourselves than meets the eye.
