Important Safety Information
For professional use only. Always follow the manufacturer's instructions for the specific shade and service. Wear suitable protective gloves and perform an Allergy Alert Test 48 hours before each colouration. ME+ reduces the risk of developing a new allergy to hair colour but does not eliminate the risk. Do not colour hair if the client has previously experienced an allergic reaction to hair colourants. Do not use to colour eyelashes or eyebrows.
