©Thinkstock/L'Observatoire des Cosmétiques

In April 2003, an exhaustive reevaluation of all the colourants used in hair dyes in Europe has been launched. At stake: to improve the safety level for consumers through the writing of a new regulation, to lower both the toxic and allergic risks, frequent for this kind of ingredients. A new step in this process, with the vote of a new Directive, which regulates 24 new substances.

Up to now, 180 substances have already been banned, and 52 more come with restrictions for use.
