[0167] Protocol:

[0168] At the time of use, each of the compositions A to C is mixed with the oxidizing composition D according to a 1:1 weight ratio.

[0169] Each of the mixtures M.sub.(A+D), M.sub.(B+D) et M.sub.(C+D) is then applied to a lock of hair containing 90% natural white hair (NW) and a lock of permanent-waved 90% natural white hair (PWNW) in a proportion of 5 g of mixture per 1 g of hair.

[0170] After a leave-on time of 30 min on a hot plate at 27 C., each lock of hair is rinsed, washed with L'Oral Professionnel Pro Classic universal concentrated shampoo, diluted to 10%, and dried.

[0171] Evaluation:

[0172] The colorimetric measurements were performed on each of the treated locks using a Konica Minolta CM-3600A spectrocolorimeter (illuminant D65, angle 10, specular component included) in the CIELab system.

[0173] In this system, L* represents the lightness: the lower the value of L*, the deeper, more powerful and more intense the colouring obtained. The chromaticity is measured by the values a* and b*, a* representing the green/red colour axis and b* the blue/yellow colour axis.

[0174] The selectivity is represented by the colour difference E between the locks of dyed natural non-permanent-waved (NW) hair and the dyed permanent-waved locks (PWNW).

E={square root over ((L*L.sub.0*).sup.2+(a*a.sub.0*).sup.2+(b*b.sub.0*).sup.2)}

[0175] In this equation, L*, a* and b* represent the values measured on the locks of dyed non-permanent-waved natural (NW) hair, and L.sub.0*, a.sub.0* and b.sub.0* represent the values measured on the locks of dyed permanent-waved (PWNW) hair. The lower the value of E, the lower and therefore better the selectivity (uniform dyeing).

[0176] The results obtained are grouped together in Table 3 below:

TABLE-US-00003 TABLE 3 Type of hair L* a* b* E Mixture M.sub.A+D NW 48.46 3.19 12.11 1.16 (invention) PWNW 47.31 3.17 11.99 Mixture M.sub.B+D NW 49.77 3.00 11.70 7.24 (comparative) PWNW 42.62 4.10 11.94 Mixture M.sub.C+D NW 48.39 2.92 12.30 8.96 (comparative) PWNW 39.50 3.83 11.70

[0177] The colouring obtained with the mixture M.sub.A+D according to the invention has E values lower than that of the colourings obtained with the comparative mixtures M.sub.B+D and M.sub.C+D.

[0178] It is thus observed that the selectivity of the colouring obtained with the composition according to the invention is better than the selectivity of the colourings obtained with the comparative compositions.

[0179] The colourings obtained with the composition according to the invention are therefore more homogeneous than the colourings obtained with the comparative compositions.
