(16) The dye compositions A4 to A5 are mixed respectively with the oxidizing composition B1 in a 1:1 ratio.

(17) The mixtures thus obtained, A4+B1 and A5+B1, are applied to locks of natural hair containing 90% grey hairs.

(18) After a leave-on time of 35 minutes at ambient temperature, the locks are rinsed with clear water, then washed with a shampoo. Finally, the locks are dried.

(19) The locks are then subjected to a test of 12 shampooing operations in order to evaluate the fastness with respect to washing.

(20) The colorimetric measurements are performed before the test, and then after the test, using a Minolta CM2600D spectrocolorimeter (illuminant D65, angle 10°, specular components included) in the CIE Lab system.

(21) The fastness with respect to washing is represented by the colour difference ΔE between the dyed locks before and after the 12-shampoo test according to the equation:
ΔE=√{square root over ((L*−L.sub.0*).sup.2+(a*−a.sub.0*).sup.2+(b*−b.sub.0*).sup.2)}
where L*, a* and b* represent the values measured on the locks of dyed hair before the test, and L.sub.0*, a.sub.0* and b.sub.0* represent the values measured on locks of dyed hair after the test.
The lower the value of ΔE, the better the fastness with respect to washing.

The mixture obtained with composition A4 according to the invention has a lower ΔE value, and thus a better fastness with respect to washing, compared with the mixture obtained with composition A5.

(39) The composition C contains 21.1% of solid fatty substances. Composition A8 according to the invention contains 21.1% of liquid fatty substance and A9 contains 53% of liquid fatty substance.

(40) At the time of use, the compositions C, A8 and A9 were mixed with a composition of hydrogen peroxide (30 Vol/9 g % of H2O2) in a ratio 1.5/1).

(41) Each of the resulting mixture was applied on highly sensitized hair containing 90% of white hair (alcaline solubility=40). 10 g of the mixture were applied to 1 g of hair.

(42) After 30 min at 40° C., the hair was rinsed, washed with a shampoo and then dried.

(43) The colorimetric measurements are performed using a spectrocolorimeter SF600X Datacolor (illuminant D65, angle 10°, specular components included) in the CIELab system wherein L* represents the intensity of the coloration. The lower L* is, the more intense the color of the hair is.

(44) The results are reported in the table below:

(46) The compositions according to the invention obtained from A8 and A9 exhibit a L* value lower than the one obtained from the comparative composition C. This means that the intensity of the coloration obtained from the composition of the invention A8 and A9 is significantly higher than the one obtained from the comparative composition C.

(47) Furthermore the mixture obtained from A9 exhibits a L* value lower than the one obtained from the composition A8, thus providing an even more intense coloration than the composition obtained from A8.
