Colourstart – Committed to colour

1x Colourstart patch test

Colourstart consists of an adhesive patch that contains two small, separate squares. One square contains a small amount of PPD (this is the positive ‘+’ part), the other contains no PPD (this is the negative ‘-‘ part) and is used for comparison only.

The patch is applied to an easily visible part of the arm at least 5 days before an appointment for hair colour. The patch is left on for at least 48 hours (2 days) and then removed. 48 hrs (2 days) later, the arm can be inspected for any sign of a reaction.

By carefully answering a simple set of questions on the colourstart passport app, Colourstart Passport can help you decide if Colourstart is suitable for you to use. Your answers may also help you make an informed decision on whether you should avoid hair colour. Colourstart Passport stores the answers to your questions and also any pictures you have taken of your test result.

This can be helpful to share with your hairdresser, beauty therapist or

barber for future reference to avoid potentially unnecessary retesting.

Colourstart Passport can be shared with any participating hair professional.
