Hair shaft, light micrograph
Hair shaft, differential interference contrast light micrograph. The outer layer of a hair shaft (the cuticle) has overlapping scales of keratin. These are thought to be important in preventing matting of the hair. Hair is made up of the protein keratin, formed from the living root embedded in the skin. As the keratin is produced, the hair shaft forms and is pushed outwards. Magnification: x1000 when printed at 10 centimetres across

EDITORS COMMENTS
This print showcases the intricate details of a hair shaft under a light microscope. The image reveals the outer layer of the hair shaft, known as the cuticle, which is composed of overlapping scales made of keratin. These scales play a crucial role in preventing tangling and matting of our hair strands. Hair, an essential part of our anatomy, consists primarily of keratin protein that is produced by living roots embedded within our skin. As this protein synthesis takes place, it gradually forms the structure of the hair shaft and pushes it outward. The magnified view captured in this photograph allows us to appreciate the complexity and beauty hidden within even the tiniest elements of our bodies. It provides valuable insights into cell biology and tissue health while also serving as a reminder that seemingly ordinary features possess extraordinary intricacies when observed closely. This remarkable micrograph holds significance not only for professionals in fields like dermatology or histology but also for anyone curious about understanding their own biological makeup. By shedding light on these microscopic wonders, Science Photo Library enables us to explore and appreciate the marvels that exist within ourselves without any commercial intent.
