Nothing is better for cleansing brushes than ammonia; it does not soften the bristles, as soap and soda do. Put a teaspoonful of ammonia into a quart of water, and soak the bristles in the solution (keeping the ivory, bone, or varnished back out of the water). The brush must then be rinsed in fresh water and dried in the air, but not in the sun.

Combs should never be washed. They may be cleansed by passing a coarse thread or card between the teeth. There is also a small brush which is used for cleaning combs.

The greatest cleanliness is necessary for all articles used for dressing the hair.

If you use ammonia in your bath, avoid wetting the hair except when necessary, because ammonia fades the hair.
