SEM of hair on scalp
Hair. Coloured scanning electron micrograph of hairs protruding from the surface of the scalp. Numerous desquamating cells (pink) are concentrically arranged around the base of the hair shaft. Hairs consist of a root which is implanted in the dermis of the skin and a shaft which represents the portion projecting from the epidermis. The shaft is divided into three concentric sheaths called the medulla, cortex and cuticle. The cuticle, the external sheath, is seen here; it is formed by a single layer of flat keratinised scales which overlap each other. Magnification: x1320 at 6x7cm size

EDITORS COMMENTS
This print from Science Photo Library provides a mesmerizing glimpse into the intricate world of human hair on the scalp. The colored scanning electron micrograph showcases an array of hairs protruding from the surface, revealing their fascinating structure and composition. At the base of each hair shaft, we observe numerous desquamating cells arranged in concentric patterns, adding a touch of pink to this microscopic landscape. Hairs are composed of two main parts: the root implanted in the dermis and the shaft projecting from the epidermis. In this image, our focus lies on the external sheath known as cuticle. The cuticle is formed by a single layer of flat keratinized scales that elegantly overlap one another like tiles on a roof. This outermost layer acts as a protective shield for each individual strand, safeguarding it against environmental stressors and damage. With its magnification set at x1320, this 6x7cm print allows us to appreciate even the tiniest details within this complex system. It serves as a reminder that even seemingly ordinary features possess extraordinary intricacy when observed under such high resolution. Whether you're fascinated by anatomy or simply intrigued by microscopic wonders, this photograph offers an awe-inspiring view into one aspect of our body's remarkable complexity – our very own scalp adorned with countless strands of hair.
