When you buy your first Patch Test, your Salon should email you an invitation to Colourstart Passport. Then, just follow these simple steps and you’ll be ready to go!

1: Set up your account

Allow at least 4 days before your next colour appointment.

Open the email invitation* from your Salon and follow the link to go to the sign up screen. 

*If you haven’t received an email, you can sign up here or you can download the Passport app:


Then, follow the on-screen instructions to register with Colourstart Passport.

2: Share your Passport

Next, select which Salon(s) you’d like to share your Passport with.

3: Take Screening Questionnaire

Answer a short health-related ‘screening questionnaire’ to check that it is OK for you to use Colourstart

4: Use your Colourstart Patch test

Follow Passport’s step by step process to use your Patch Test and record the results.

5: Upload photos

Apply and remove the Patch when Passport tells you to and make sure you upload images when prompted.

6: Record result

Finish by confirming whether you’ve experienced a reaction to your Colourstart Patch Test.

7: No reaction? Say hello to Colour Freedom!

If you don’t experience a reaction to the Test you’ll get a green ‘OK to colour hair’ Passport, which any participating Salon will accept instead of a standard test, even for walk-in colour and repeat colourings.
