I am a consultant in cosmetics based in the UK. I have been consulting for the last 10 years since leaving Clairol and before that working for Unilever.
One of my specialist areas is hair coloring and I read your article “A Colorful History” in the latest on-line edition of Happi.
The early days of coloring based on oxidative chemistry and (many) synthetic organic chemicals are interesting and a little unclear. What is clear, however, is that the early basis of Schueller’s products was not PPD. Indeed the early name was “The harmless French hair dye company” (or something similar).The main support for this being that the products did not contain PPD that he believed to be dangerous (or at least that was the marketing position).
