As men has realized from very early times, a full head of well-cared-for hair can certainly enhance his appearance. It can accomplish a wide range of becoming physical effects from softening the contour of a face to distracting from the lines of age. Psychologically, it is quite significant in influencing the impression others have of a man.
Yet, we do not have hair for adornment alone. It has a far more important significance--that of protection. Hair is found over every area of the body, with the exception of only the palm, soles, lips, and eyelids. It grows for a reason; in fact, for many reasons.
The shorter, bristly hair of the eyebrows protects the eyes by diverting sweat, while the eyelashes function to ward off dust particles and the glare of light.
Helping in the evaporation of body perspiration is a finer, downy-soft hair called lanugo hair, found on the cheeks, forehead, and nearly all areas of the anatomy.
The scalp grows a much longer type of hair. In the absence of at least a partial covering of this hair, its function cannot be carried out. It was intended as a protective coating or padding. It provides thermal insulation against the cold, wind, rain, and serves in an opposite capacity, when required, by offering atmospheric insulation from the heat and direct sunshine. In addition, this hair controls the sweat and secretions of the scalp.
To claim that the desire to retain one's hair, therefore, is merely an expression of vanity, based on social or aesthetic conditioning, is to err greatly. The presence of hair is a definite necessity for a man.
