Dyeing The Hair. Dyeing the hair is pernicious, whatever the medium may be that is employed. In cases were cosmetics become necessary, from fashion or defect in the hair, the simplest and most harmless are always the best. The hygienic treatment of the hair consists in its cleanliness and that of the scalp, and especially, as Dr. Burgess says, in the strict observance of a precept, which applies to everything connected with the management of the human frame. Wo, however, give a receipt or two.
To Dye Hair Black. Take two drachms of silver, half an ounce of steel-tilings, and an ounce of nitric arid, and eight ounces rain water. Pour off the supernatant liquor, which constitutes the dye. Apply by brushing with a close brush. Although there is a great objection to nitrate of silver a dye, from its liability to darken the skin, nevertheless it is very far preferable to caustic earths, from their almost certainty to act as depilatories. One said to be free from any injurious effect and now in leral use, is composed of the following: - Powder well in a mortar some litharge or vitrified oxide of load, with some lime; these mix in water, in the proportion of eighty-five parts by weight of the former to fifteen parts of the latter. The manner of using it is as follows: - Wash the hair with warm water and soap to free it from grease, then dry it well. The hair is then to be covered with this mixture of the consistence of cream, beginning at the roots. Four folds of soft brown paper are then to be placed over the whole, and secured by an oil-skin cap. The hair must remain in this condition from three to six or eight hours, according to the depth of shade required ; and the cap may then be removed. Some of the dye will fall out, and the rest must be combed and brushed out when the hair is dry. Do not wash the hair with water for three or four days after, as it irritates the skin. As the hair grows, the parts next the roots will be undyed, and will require the whole to be redyed every three or four months.
