Why Colourstart?

Colourstart is recommended for use across all colour brands to create that ‘wow’ factor. Colourstart can be applied at home and is an alternative to standard hair colour allergy testing.

Clinically proven, fully regulated – your safety comes first

Safety always comes first. Licensed by the MHRA (Medicines and Healthcare products Regulatory Agency), Colourstart is the only clinically proven screening test for hair colour (PPD) allergy in the UK.

Salons that use Colourstart are serious about safeguarding your health and well-being


Use at home, maybe just the once

Colourstart’s unique use-at-home design means no more Salon visits just to get a test. Even better, with our Passport app you might never need test again (provided your health status doesn’t change between colourings).

Colourstart puts you in control, you choose when and where you test

Complete creative freedom

The single one-off Colourstart test applies to all brands and colours; meaning you can use whatever colour you want, whenever.

One test, limitless colour choices!

Colour any time, any place – your passport travels with you

Participating Colourstart Salons will always accept a green ‘OK to colour hair’ passport, even for walk-ins, whether you are their client or not. So even if you travel you’ll still be colour-ready!
