Hair dyes: a debate about their safety

©L'Observatoire des Cosmétiques

Hair dyes are often a cause for concern about their safe use, due to the risk of allergy and to their toxic potential.

Three dyes are specifically targeted in this article: Toluene-2,5 Diamine, Toluene-2,5 Diamine Sulfate and Paraphenylenediamine ( INCI : p-Phenylenediamine); the journal also detected carcinogenic formaldehydesome formulas. And the journal advises users against 17 of the tested products, finding only one as just "acceptable".
