Coloured SEM of a section through a hair follicle
Hair follicle. Coloured scanning electron micrograph (SEM) of a cross-section through a hair follicle below the skin surface. At upper centre is a shaft of hair (green) surrounded by the epidermis (red), the upper layer of skin. The epidermis is surrounded by the dermis, the lower skin layer. Hair is made up of a fibrous protein called keratin. The hair shaft is covered with overlapping keratin scales or plates (as seen) which are thought to prevent hairs from matting together.

EDITORS COMMENTS
This print showcases a coloured scanning electron micrograph (SEM) of a section through a hair follicle, revealing the intricate details below the skin's surface. At the upper center of the image, we can observe a vibrant green shaft of hair surrounded by the epidermis, which is depicted in striking red tones. The epidermis represents the outermost layer of our skin and acts as its protective shield. Enveloping this crucial layer is the dermis, which constitutes the lower skin layer. The composition of hair itself is truly fascinating; it consists primarily of keratin, a fibrous protein responsible for its strength and resilience. As we zoom into this microscopic view, we notice that the hair shaft is adorned with overlapping keratin scales or plates. These unique structures are believed to play an essential role in preventing hairs from tangling or matting together. Although we are not provided with information regarding magnification levels for this particular SEM image, it serves as an awe-inspiring reminder of how intricately designed our bodies are at even their smallest scale. This photograph offers us a glimpse into one aspect of human anatomy while simultaneously highlighting both scientific and artistic beauty—a testament to Science Photo Library's commitment to capturing remarkable images that inspire curiosity and wonder about our world.
