(3) Visual Evaluation of the Stability of the Compositions

(4) The stability of the dye compositions was evaluated by observing them at T0 and then after 48 h at room temperature (25° C.) and then after 2 months of storage at 45° C.

(5) TABLE-US-00002 Composition A1 Composition A2 Observation at T0 (immediately Translucent gel Translucent gel after preparation) at room Homogeneous (no Homogeneous(no temperature (25° C.) phase separation) phase separation) Observation after 2 months at Translucent gel Translucent gel 45° C. Homogeneous (no Homogeneous (no phase separation) phase separation)

(6) It is observed that composition A1 (comparative) and composition A2 according to the invention are homogeneous and form a translucent gel at T0. After 2 months at 45° C., compositions A1 and A2 according to the invention are stable and in gel form; they are homogeneous and translucent. Comparative composition C5 in which the scleroglucan gum has been replaced weight-for-weight with another thickener, hydroxypropylcellulose, is not stable, and is liquid. Thus, it is not homogeneous; phase separation of these compositions is observed as early as T0.

EXAMPLE 2

(7) Compositions A1 and A2 of example 1 were mixed with 1 times their weight of 20-volumes oxidizing agent (6 g % of H2O2 AM); the mixture thus obtained was applied to locks of natural hair containing 90% white hairs.

(8) The “mixture/lock” bath ratio is, respectively, 10/1 (g/g).

(9) The leave-on time is 30 minutes, on a hotplate set at 27° C. On conclusion of the leave-on time, the locks are rinsed and then dried under a drying hood at 40° C.

(10) The color of the locks was evaluated in the CIE L* a* b* system, using a Minolta CM3600D spectrocolorimeter

(12) The mixture obtained using composition A2 according to the invention gives a higher C* value, and thus better chromaticity than the mixture obtained using the comparative composition A1.
