Yellow hair color dyeing composition having improved wear properties |
| abstract |
Oxidative dyeing of hair to a natural blonde or yellow coloration with exceptional wearing properties can be obtained y use of a system for oxidati ve hair coloring in which the hair coloring system utilizes a compound of the formula (I) wherein R1 and R2 are independently H; C1-4 alkyl, optionally substituted with one or more hydroxy- or amino groups; R1 and R2 may form a 5- or 6-membered heterocyclic ring, optionally containing one additional N- or O- heteroatom in the ring as a primary intermediate and a compound of the formu la (II) wherein R1 and R2 are independently H; C1-4 alkyl or hydroxy-alkyl as a coupler and optionally a yellow direct dye or a known oxidative yellow dye.< /SDOAB> |
