CLEANSING THE HAIR: LIPIDIC SURFACE FILM

Health Area

It is known that sebum, produced by the sebaceous glands, reaches the surface of the epidermis via the pylosebaceous duct. Once it reaches its destination it emulsifies with sweat forming a thin coating known as the hydrolipidic surface film. The equilibrium between sebum and the surface is of basic importance for the protection of the skin from aggressive external agents, be these chemical-physical, bacterial or mycotic, and for the maintenance of normal acidity, an optimum state of hydration and the elasticity and plasticity of the skin. The surface skin lipids film, which is naturally present on the scalp, covers the hair smaft, making it soft, shiny and combable. The excessive presence of this hydrolipidic film on the scalp, but especially on the hair shaft, makes the hair difficult to comb and causes opacity and a "feeling of dirtiness", which significantly reduces the basic function which hair plays as an important factor in sexual attraction.
