514. _To purify and beautify the Hair._--An excellent means of keeping the hair sweet, clean, glossy, and curly, is to brush it with a rather hard brush dipped by the surface only in eau de Portugal ("Portugal water"). In order to have it fresh and of fine quality, take a pint of orange flower water, a pint of rose water, and half a pint of myrtle water. To these put a quarter of an ounce of distilled spirit of musk, and an ounce of spirit of ambergris. Shake the whole well together, and the water will be ready for use. Only a small quantity should be made at a time, as it does not keep long, except in moderate weather, being apt to spoil either with cold or heat. 515. _To promote the Growth of Hair._--Mix equal parts of olive oil and spirits of rosemary, and add a few drops of oil of nutmeg. If the hair be rubbed every night with a little of this liniment, and the proportion be very gradually augmented, it will answer every purpose of increasing the growth of hair, much more effectually than can be attained by any of the boasting empirical preparations which are imposed on the credulous purchaser. 516. _Curling Liquid for the Hair._--When the hair will not curl naturally, the curling irons should not be used; they only extract the moisture, and render the hair crisp and harsh. An excellent curling liquid is the following:--Put two pounds of common soap, cut small, into three pints of spirits of wine, with eight ounces of potash, and melt the whole, stirring it with a clean piece of wood. Add some essence of amber, vanilla, and nevoli, about a quarter of an ounce of each, to render the fluid agreeable. The liquids which are sold for the professed purpose of assisting in curling the hair, are chiefly composed of either oily or extractive substances. 517. _To prevent Hair from falling out._--Make a strong decoction of white-oak bark in water, and use it freely. It is best to make but little at a time, and have it fresh at least once a fortnight.
