False colour SEM of knotted human hair
Knotted hair. Colour scanning electron micrograph (SEM) of a knotted strand of human hair. Hair is a fibrous protein (keratin), which develops out of a tubular hair follicle found in the epidermis of the skin. The shaft, the visible part, consists of three layers; an outer layer or cuticle, which appears scaly in normal hair. Beneath is the cortex containing hair colour pigments. The medulla forms the central core, which may be hollow. Hair cells are dead except for a layer at the base of the root, which divides to form new cells, pushing the older ones upward. Magnification: x60 at 35mm size

EDITORS COMMENTS
This print showcases the intricate beauty of knotted human hair in a false color scanning electron micrograph (SEM). The image reveals the remarkable structure of hair, which is composed of fibrous protein called keratin. Each strand develops from a tubular hair follicle located within the epidermis of our skin. The visible part of the hair, known as the shaft, consists of three distinct layers. The outer layer, called cuticle, appears scaly and serves as a protective barrier for the inner layers. Beneath it lies the cortex, which contains pigments responsible for our unique hair colors. At its core lies the medulla, which may sometimes be hollow. Interestingly, these strands are made up entirely of dead cells except for a small layer at their base where new cells continuously form and push older ones upwards. This constant renewal process ensures healthy growth and maintenance. With an impressive magnification level of x60 at 35mm size, this SEM image allows us to appreciate even the tiniest details that make up our locks. It's truly fascinating how something so ordinary can reveal such complexity when viewed through scientific lenses. This mesmerizing photograph by Science Photo Library provides us with an extraordinary glimpse into one aspect of our own anatomy – reminding us once again that there is always more than meets the eye in nature's creations.
