Medicated Shampoos

These shampoos are used to correct any disorder of secretion in the scalp. If you have dry hair, choose a shampoo based on cod oil, tar or lecithin. If you have oily hair, a shampoo containing sulphur or essence of cedar is best. There are dry and coloring shampoos widely used in western countries. Dry shampoos come in an extremely fine powder form which is sprinkled over the hair and then removed by very thorough brushing. Their main advantage is that no wetting of the hair is required. They consist of a mixture of synthetic detergent in powder form and mineral salts. Mostly sodium salts are used which absorb fatty matter. Thus the hair can be cleaned without too frequent washing, and because of this they are particularly recom­mended for oily hair.

Coloring shampoos have become very popular in recent years for brightening the color of the hair. They are in fact good shampoos with a detergent base to which has been added either a bleach or a dye which is much less harmful than the real dyes because it does not penetrate the hair but only covers it with a thin coloring film. Coloring shampoos are generally harmless, but they can affect those who are susceptible to allergies, by causing an eczema on the face and swelling or irritation on the scalp. To avoid these severe allergies, do not use coloring shampoos during periods, pregnancy, menopause, ovarian upsets, and skin troubles. .

To carry out a shampoo properly, begin by soaking your hair in hot (not too hot) water. Too hot water is not good for the hair or the scalp. Pour on to the hair a small quantity of shampoo and rub the scalp with the tips of your fingers vigorously. If your hair is long or very thick, slip your fingers right through the hair to the scalp itself, and rub it vigorously but not roughly. Next rinse completely with hot water, and again apply a Jot of shampoo. Rub in, but this time more with the hands flat. Do not penetrate through to the scalp, but gently rub the half. The shampoo should foam cleanly. If not, apply more shampoo for the third time. The rinsing which follows must be very thorough. Rinsing should not stop until the water from this last rinse is completely clear. At the slightest trace of soap or foam, at the slightest tingling from the scalp, do not hesitate to carry out an extra rinse.

Next you should wring the hair, but never twist it, in a thick towel. Wrap the dry towel like a turban around your hair. A hair dryer can also be used for this purpose, but avoid too hot air.
