Enabling hair colouring with confidence across UK hair salons

The Vision

Colourstart is the world’s first medically licensed test sold direct-to-consumer for hair colour allergy. The product is a patch test applied to your skin, used to screen for allergy to one of the common ingredients (PPD) in hair colourants.

Trichocare Diagnostics approached mmtm looking to develop an application to facilitate this patch test process.

The result is Colourstart Passport, a web and mobile app used by thousands of people daily to record the results of their Colourstart patch test. They start by answering a questionnaire and then record the patch application and any reaction via a photo. Getting gentle reminders throughout the process.

Prototyping to validate the business case

We initially conducted a product design sprint with Trichocare Diagnostics to validate the Colourstart Passport business strategy, the app’s concept, and its initial feature set - all within one week!

The prototypes were tested with industry professionals and potential customers to ensure we built the correct product with no additional fat, providing a cost-effective launch.

Data-Driven Growth

Big data analytics

As Colourstart Passport has grown, the app is now generating anonymised data insights about the hair professional industry while providing users an easy-to-use experience.

We continue to work closely with Trichocare to analyse these trends and use them to inform data-driven decisions to improve the product and overall business strategy.

Mobile App

In 2022, we launched the Colourstart Passport mobile app for iOS and Android after customer demand.

The mobile app gives Colourstart real estate on a customer's device and dramatically increases their likelihood of recording a patch test before their next appointment.

Integrating with major salon management systems

Major salon management platforms such as SalonIQ and Phorest are now integrated with Colourstart Passport. Thus enabling a more streamlined user experience for those working in salons.

Removing this barrier to entry has enabled growth for Trichocare's business. We designed and built the API and provided comprehensive documentation and training.
