Many preparations are given to restore the color to dark hair when it is lost through ill health or over-study. The fashionables to-day, with true taste, admire gray hair when in profusion, and deem it distinguished when accompanied by dark eyes, to which the contrast adds a piercing lustre. But those who consider themselves defrauded of their natural tints may use this recipe: Tincture of acetate of iron, one ounce; water, one pint; glycerine, half an ounce; sulphuret of potassium, five grains. Mix well, and let the bottle remain uncovered to pass out the foul smell arising from the potassium. Afterward add a few drops of ambergris or attar of roses. Rub a little of this daily into the hair, which it will restore to its original color, and benefit the health of the scalp. Ladies are annoyed by the tendency of their hair to come out of crimp or curl while boating or horseback-riding. The only help is to apply the following bandoline before putting the hair in papers or irons: A quarter of an ounce of gum-tragacanth, one pint of rose-water, five drops of glycerine; mix and let stand overnight. If the tragacanth is not dissolved, let it be half a day longer; if too thick, add more rose-water, and let it be for some hours. When it is a smooth solution, nearly as thin as glycerine, it is fit to use. This is excellent for making the hair curl. Moisten a lock of hair with it, not too wet, and brush round a warm curling-iron, or put up in papillotes. If the curl come out harsh and stiff, brush it round a cold iron or curling-stick with a very little of the cosmetic for keeping stray hair in place, or cold cream. To the recipe given in the last chapter another is added, of perhaps finer proportions: Oil of sweet almonds, five parts; spermaceti, three parts; white wax, half a part; attar of roses, three to five drops. Melt together in a shallow dish, over hot water, strain through a piece of muslin when melted, and as it begins to cool beat it with a silver spoon till quite cold and of a snowy whiteness. It is well to rub it smooth on a slab of marble or porcelain before putting in glass boxes to keep. For the hair use seven parts of almond-oil to the other proportions named. The secret of making fine cold cream lies in stirring and beating it well all the time it is cooling.
