Hair colourants have been extensively studied and their safety has been repeatedly confirmed by independent scientists and regulatory authorities alike. Hair colourants themselves are regulated under the strict EU Cosmetics Regulation and are safe to use when the instructions are followed carefully.
Reactions to hair colourants can occur for a very small number of people, in the same way that some individuals can react to a variety of foods and natural substances.
Allergic reactions to hair colourants are extremely rare. Of those individuals who have the potential to react to a hair colourant, potential reactions can be detected by carrying out the Allergy Alert Test, as directed, 48 hours before you wish to use the product. The Allergy Alert Test must be completed before each colour application, even if you have previously used the same hair colourant or the colourant of any other brand.
