While we don't verify specific claims because reviewers' opinions are their own, we may label reviews as "Verified" when we can confirm a business interaction took place. Read more
To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software. This technology is designed to identify and remove content that breaches our guidelines, including reviews that are not based on a genuine experience. We recognise we may not catch everything, and you can flag anything you think we may have missed. Read more
Company details
Written by the company
Colourstart is an advanced allergy screening system controlled by consumers and accepted by UK hairdressers. It replaces the 48 hour allergy alert test recommended by manufacturers of hair colour and the need to repeat a test if you change salon or colour brand. Colourstart is licensed by the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) as the only clinically proven method of screening for potential allergy to p–Phenylenediamine (PPD), a common ingredient hair colour. You set up and own your Colourstart Passport which records the testing process and stores results for you to share with your hairdresser of choice. Having a Colourstart Passport means you don't need to repeat an allergy test unless your salon recommends it, making it an ideal universal solution for complete creative freedom. Tests can be ordered online directly at www.colourscreen.me or any participating salon in the UK. For further information on Colourstart go to www.colourstart.com or call 0330 3905888.
