Colourstart is a ready-to-use Patch Test that can show if you may be allergic to PPD, one of the most common ingredients present in hair colourants. Available to purchase at store.toniandguy.com or your local TONI&GUY salon and accepted everywhere.
The Test Patch must stay on your arm for 2 days and be done at least 4 days before your colour appointment. The process must be recorded online using the Colourstart Passport App and shared with TONI&GUY.
Colourstart Passport allows you to update your allergy test record ahead of future colour treatments by carefully completing a set of health-related questions.
You will not be required to repeat the use of the Colourstart Patch Test if your health status remains unchanged.
