Hair Wash to Cleanse the Scalp
June 11th, 2024
Add six drops of aqua ammonia to a wine-glass of warm water, and with a small bit of sponge or flannel wash the head thoroughly, dividing the hair into partings, so that all the skin is wetted. This not only cleanses the scalp quickly, but also preserves the color of the hair. It can be applied once a week, before going to bed, with very good effect.
