What layer of skin is referred to as the epidermis?

The epidermis is indeed referred to as the outer layer of skin. This layer is crucial as it serves as the first line of defense against environmental factors such as bacteria, UV radiation, and chemical exposure. It is composed primarily of keratinocytes, which produce keratin, a protein that helps protect the body. The epidermis also plays a role in the regulation of moisture and contains melanocytes, which are responsible for the pigmentation of the skin. Understanding the significance of the epidermis can guide practitioners in the field of braiding and hair care, particularly when considering the health and condition of the scalp and hair.
