1695. Directions for Application
The solution No. i. is first applied to the hair with a tooth brush, and the application continued for fifteen or twenty minutes. The solution No. ii. is then brushed over, a comb being used to separate the hairs, and allow the liquid to come in contact with every part. Care must be taken that the liquid does not touch the skin, as the solution No. ii. produces a permanent dark stain on all substances with which it comes in contact. If the shade is not sufficiently deep, the operation may be repeated. The hair should be cleansed from grease before using the dye.
