The application of electrochemical techniques to the determination of common hair dye constituents was investigated. Cyclic voltammetry was used to probe the electrode response to p-phenylenediamine (PPD), 4-chlororesorcinol and m-aminophenol with square wave voltammetry used to effect quantitative measurements. The nature of the electrode response was characterised and issues of surface fouling resulting from the deposition of electrogenerated reaction products were addressed. A procedure designed to allow the facile determination of PPD in hair care products is presented.
