Colourstart Allergy Screening System

Following 15 years of development with leading dermatologists, Colourstart sets a new standard for professional allergy screening.


The Colourstart system combines the first clinically proven test for allergy to hair colour with a license from the Medicines and Healthcare products Regulatory Agency (MHRA) and a fully auditable Passport technology platform.

This universal system of testing is a complete game changer for professional salons. For the first time, business owners can train staff and educate clients with a compliant system for use across all colour brands, as well as demonstrating duty of care and insurance compliance without inhibiting creative freedom.

You can order Colourstart online at or direct from their salon. It comes in the form of a PPD patch application at home. Tests should remain on for 2 days and any reaction recorded 2 days after removal. Redness, itching or inflammation indicate allergy to PPD and colouring is not recommended; even if the intended colour does not contain PPD.

Clients record the whole process using the free, fully auditable Colourstart Passport App. Their green ‘OK to Colour’ status is also redeemable at any participating salon. Future colours require clients to complete a simple rescreening questionnaire. Green status may be re-issued if there are no changes.

Colourstart is compatible with any colour manufacturer that recommends a patch test. This makes it an ideal universal solution to skin testing in a professional setting.

The process of patch testing and interpreting a skin test can present a risk in salons. This is particularly the case with the application of more than one colour. Businesses using Colourstart get coverage from most major insurers and where they are not get direct cover from a special Colourstart Vendors Extension.

Colourstart gives colourists peace-of-mind to unleash their complete colour creativity.
