The process of colorau00c7u00e7o fibres queratu00cdnicas, composiu00c7u00e7o cosmu00c9tica for colorau00c7u00e7o queratu00cdnicas fibres and device with several compartments.The present invention is engaged in a process of colorau00e7u00e3odas fibers queratu00ednicas by application on these fibers (I) at least one derived from ortodifenol, (II) at least one metal salt, (III) at least one hydrogen peroxide or at least one generator system of PE Ru00f3xido of hydrogen.(IV) at least (BI) carbonate and V) at least alkalinizing agent different from the (BI) carbonate. Another object of the present invention is a device with several compartments which comprises the ingredients (I), (II), (III), (IV) and (V).This hair dyeing process allows to obtain best colors more homogeneous colour, hard and not affecting the cosmetic propriradades fibres queratu00ednicas from extract of natural ortodifenu00f3is in particular.
