Hair and nails are predominantly epithelial structures derived from the primitive epidermis and made up of keratinous fibrils embedded in a sulfur-rich matrix. Keratin, the same protein that makes up hooves, claws, and horns in animals, is also found in hair and skin. The nail unit is comparable in several respects to a hair follicle sectioned longitudinally and laid on its side.

What You'll Learn
Hair and nails are made of the same material
Hair and nails are predominantly epithelial structures derived from the primitive epidermis and made up of keratinous fibrils embedded in a sulfur-rich matrix. The formation of a nail begins inside a part of the fingertip called the nail root where the cells which will eventually form the nail plate gradually die, harden and push out of the skin. As the older cells are compacted and pushed out of the skin by the formation of new cells, they take the hardened, flattened form of the fingernail.

This is where the cells which will eventually form the nail plate gradually die, harden and push out of the skin.
Hair and nail changes are often associated with malignancy and cancer treatment. Koilonychia is a condition that can affect both hair and nails. It is a deformity of the nail apparatus that can be observed in patients with alopecia areata.
Non-infectious inflammatory disorders of the nail apparatus can also be observed in patients. Hair and nail changes can also be observed in patients with other medical conditions such as dermatological disorders.
Hair and nails are often used as diagnostic tools in patients with malignancy and cancer treatment-related hair and nail changes. The changes in hair and nail growth can be observed and recorded to monitor the progression of the disease and evaluate the effectiveness of the treatment.
