The protective wrapping of each body parts that lies outside every single organ is called skin. It covers the entire body and therefore considered as one of the largest organs. The features of the skin are that it is airtight, water-resistant and flexible barrier that restricts the outer environment from impacting the internal organs of the body. The internal environment of the body stays sustainable, safe and stable with the help of skin. Skin can be categorized into three parts including the dermis, epidermis, and subcutaneous layer.
The external layer of the skin is known as epidermis. Epidermis can be explained as the mixture of numerous cells that are closely packed with each other. The particular part or location of the body actually depicts the thickness of the epidermis. Body parts that are soft but thick at the same time such as palm and soles possess epidermis at large amount. It is therefore such organs becomes more flexible and thicker as compared to other organs and simultaneously helps such parts in resisting mechanical injuries. While on the other hand, epidermis located at the eyelids makes it extremely thin which also helps the organ to have full movement. Advantages of epidermis incorporates avoidance from water loss and fluids of body, high resistance from injuries caused from mechanical or chemical work, and mainly the protection against bacteria, viruses and parasites infections. The pigment that exists within the epidermis protects the skin from ultraviolet radiation.

With the help of the tiny cuts, the glands are exposed onto the surface. The hair grows all over the body through hair follicles except the two body parts; sole and palms.
Underneath the epidermis lies the dermis that is comparatively 20 to 30 times denser than the epidermis. The dermis constitutes of the specialized proteins that are placed in the form of thick network. These specialized proteins are elastin and collagen that are systemized into fibers with variance in their sizes and properties. The fibers are surrounded by multifaceted gel of various proteins. Overall, the entire system is referred to extracellular matrix. The major components that lies within the extracellular matrix incorporates nerves, blood, lymphatic vessels, sweat glands and the lowest part of the hair follicles.
Subcutis (subcutaneous layer)
Subcutis is considered as one of the specialized areas under the dermis that consist of networking among collagen fibers and fat cells (adipocytes). The subcutis helps in sheltering the body parts from exterior trauma and insulates from the cold weather. The layer is therefore regarded as main area for the storage of fat and energy. From the layer of subcutis passes several lymphatic and blood vessels together with the nerve vessels.

Sebum that is produced from the fats is one the oily product that is quite healthy for the protection of skin as it helps in moisturizing the skin and maintains the shine and health of the hair. Sometimes, applying excessive amount of sebum results into clogged pores and acne and ultimately the skin becomes much oily.

The cuticle gradually wears away at the time when hair gets damaged. In result, cortex is exposed that lies between the hair cuticle and the medulla. The damage can have multiple impacts such as hair splits, hair breaking, and mainly the visibly unhealthy hair. Some of the essential factors that contribute in chemically damaged hair incorporate hair coloring, hair relaxants, and perms.
