While many of us may think that the scalp is little more than the skin that our head hair grows out of, the truth is that it’s so much more than that. The scalp is made up of 5 unique layers, the skin, dense connective tissues, epicranial aponeurosis, loose areolar connective tissue, and periosteum. The first three layers of the scalp are connected tightly together, so much so that they move as a single unit.

Skin

You are likely very familiar with this layer. Our skin is considered an organ because, by definition, an organ is a contained group of tissues dedicated to performing a particular function, like how our hearts beat to help disperse oxygen throughout our bodies our skin acts as a protective barrier. Many microorganisms, chemicals, radicles, and other things that could make us sick are thwarted by the skin. Hair follicles are contained within the skin, therefore the health of your skin can have a direct impact on the health of your hair.  

Dense Connective Tissue

As the name suggests, dense connective tissues of the scalp connect the skin to the third layer of the scalp. Blood vessels are attached to this layer; as such, the blood vessels are not able to constrict all the way if they are cut. It is for this reason the scalp can bleed profusely should it be injured The blood vessels are also responsible for providing nutrients to the hair follicles.

Epicranial Aponeurosis

This layer of the scalp is a tough layer of dense tissues that covers the forehead as well as the top and upper-rear area of the skull. The epicranial aponeurosis acts as an attachment site for the muscle responsible for the movement of the eyebrows and forehead; this makes it possible for the forehead to wrinkle.

Loose Areolar Connective Tissue

This allows the top three layers of the scalp to slide of the final layer of the scalp. The loose areolar connective tissues are made up of a network of specialized fibers, tissues, and collagen.

Periosteum

This layer is a dense layer of tissues that cover and envelope the bone attaching it to the muscles. This layer is actually comprised of two parts the fibrous periosteum, which is the layer furthest away from the bone. And the osteogenic periosteum which is the layer that resides right above the bone. The fibrous layer, as the name implies, consists of densely packed tissues and contains nerve endings and blood vessels. The osteogenic layer is not as tightly packed, but it does contain beneficial cells that help bone growth and repair bones from damage.
