Alternatives to Chemical Based Dyes
It has been recorded historically that ancient civilizations dyed their hair using plants. One of the most well known is henna. Others include cassia and leeks [3]
Presently, there are some companies that do sell alternate based dyes for people that are sensitive to PPD, a chemical found in most hair dyes. [4]
There are also said to be non-toxic safer products that avoid the side-effects of chemical based dyes. The safer alternatives generally have fewer chemicals or are plant based and do also have temporary, semi-permanent and permanent options. However, these products typically do not last as long as chemical based dyes. [5] [ hotpotato's advice column | Ask hotpotato A Question ]
