We understand that coming into the salon for a patch test every 6-12 months can be inconvenient, and next year, colour manufacturers are updating their testing requirements. Soon, patch tests will need to be mixed with peroxide, applied on your forearm, and left uncovered for 45 minutes. Additionally, we’ll only be able to test one colour brand at a time, which may mean multiple trips to the salon.
After thorough research and testing, we’re excited to introduce Colourstart as our new solution for allergy testing!

⭐ Colourstart is licensed by the MHRA (Medicines and Healthcare products Regulatory Agency) and is the only clinically proven screening test for hair colour (PPD) allergy in the UK.
⭐ With Colourstart’s convenient use-at-home design, you don’t need to visit the salon for testing.
⭐ It’s a one-time test that lasts a lifetime – no retests needed (as long as your health status doesn’t change between colourings).
⭐ This single test covers all colour brands, giving us the freedom and flexibility to choose the best colour for you each time.
⭐ Tests are a one-off £15.
⭐ Once you have your Colourstart Passport, you can share it with any participating Colourstart salon, with no need to purchase another test. Already have a Colourstart Passport? Simply share your Passport with us as your hair professional and you’re ready to go!
