Hair Colour How It Works
ALLERGY TEST IMPORTANCE
Before dyeing your hair, an allergy test MUST be carried out 48 hours before.
You will find all the information on how to carry out the allergy alert test on the leaflet inside your hair dye box or you can find ‘How To’ videos on the Be Colour Safe website: Allergy Alert | Hair Allergy Test | Be Colour Safe
Always refer to the colourant box for safety instructions
