Hair - Texture



Each individual hair is made up of nonliving cells that contain a tough protein called keratin . Hair texture differs from one part of the body to another. In some areas, it may be soft and downy; in others, tough and bristly. Hair texture also differs between the sexes, among individuals, and among the different races.

If an individual hair is oval in cross-section, it is curly along its length. If the cross-section is round, the hair is straight. Thick, wiry hair is usually triangular or kidney-shaped. The fineness or coarseness of hair texture is related to its natural color.

Curling

Anyone using a home permanent preparation should read and follow instructions with great care. If a new brand is tried, the instructions should be read all over again, since they may be quite different from the accustomed ones.

Electric curling irons are not safe, because they may cause pinpoint burns in the scalp that are hardly noticeable at the time but may lead to permanent small areas of baldness. The danger can be minimized, however, if instructions for use are followed exactly. It is especially important that the iron not be hot enough to singe the hair. Setting lotions used with rollers or clips have a tendency to dull the hair unless they are completely brushed out.

Straightening

The least harmful as well as the least effective way of straightening the hair temporarily is the use of pomades. They are usually considered unsatisfactory by women because they are too greasy, but are often used by men with short, unruly hair. Heat-pressing the hair with a metal comb is longer-lasting but can cause substantial damage by burning the scalp. The practice of ironing the hair should be discouraged, since it causes dryness and brittleness, with resultant breakage. Chemical straighteners should be used with great care, since they may cause serious burns. Special efforts must be made to protect the eyes from contact with these products.
