Yamá Expert Black Carbon Bleaching Powder 300g

The Black Carbon Bleaching Powder Yamá Expert has an innovative bleaching concept thanks to its black pigmentation which enhances the cooling of the tone during bleaching, excluding and neutralizing the appearance of unwanted yellow reflections, as the charcoal present in its formulation acts as a natural Detox in the hair, as well as having purifying properties allowing it to create a more neutral base on which the professional can work more safely. It opens up to 9 shades and does not raise dust during use, thanks to the Dust Free system.
