Patch Test

The At Home Colourstart 5 Day Allergy Test is a ready-to-use Allergy Alert Patch Test, that can show if you may be allergic to PPD, one of the most common ingredients in hair colourants.

The Test Patch must stay on your arm for 48 hours and be done at least 5 days before your colour appointment.

The test results must be recorded on your colourstart Passport online on Day 5 and shared with Catherine Boden Salon.

A test showing it is safe to apply colour will be valid for 120 days. Please allow a minimum of 2 working days for delivery, and review consultation questions before you buy.
