After suffering 18 years of an on off allergy I have been told that I have an intolerance to PPDs which are found in hair dye. I was advised that the darker hair dyes contain more PPDs than the lighter shades. I have treated my hair for 18 years with the lighter shades and am not keen to stop just yet.
Does anyone know how to colour treat hair and avoid the reaction to PPDs? Would prefer to continue with visits to salons rather than DIY
