Alternatives to industrial tints
Ancient civilizations dyed their hair using plants. Some of the most well known are henna, indigo, Cassia obovata, senna, turmeric and amla. Others include katam, black walnut hulls, red ochre and leeks.
Alternate based dyes are available for people sensitive to PPD, a chemical found in most hair colors.
Products that avoid the side effects of most industrial tints are available. The safer alternatives generally contain fewer potentially toxic compounds or are plant based. Temporary, semi-permanent and permanent exist with the same persistence as the industrial versions. In practice the results produced by these products often do not last as long as industrial tints. Allergic reactions are possible even from "natural" vegetable dyes.
