Colourstart Patch Test
You must read the Colourstart page on our website which will explain how to use and upload your results on the Colourstart passport.
Colourstart Patch Test is a clinically proven patch test which screens for allergy to the hair colour ingredient para-phenylenediamine (PPD.). It is easy to use, as simple as applying a plaster!
Rather than visiting the salon for a pre-appointment test, Colourstart is applied at home.
