Covering the surface of your head, the scalp, extends from the top of your forehead across to the epicranial aponeurosis of the head. Laterally, it reaches down to the external auditory meatus and zygomatic arch (cheekbone of the skull). The scalp consists of 5 distincts layers: the skin, connective tissue, the epicranial aponeurosis, loose areolar tissue and the pericranium. The upper layers of the scalp can slide over the connective tissue beneath them, which is why the skin on your head has some ‘movement’.

The scalp is obviously hairy and has many sebaceous glands (oil glands) scattered across it. This density at which these glands are found means that the scalp can commonly be affected by sebaceous cysts. Scalp hairs protrude from structures known as hair follicles, which are situated in the dermis of the scalp. The hair follicle is comprised of layers of cells that work together to support and form the hair shaft.
