[0384] The oxidizing composition B was prepared from the ingredients of which the contents are indicated in the table below:

TABLE-US-00002 TABLE 2 Ingredients B SODIUM SALICYLATE 0.035 TETRASODIUM PYROPHOSPHATE 0.04 HYDROGEN PEROXIDE 6 CETEARYL ALCOHOL 2.28 CETEARETH-25 0.57 TETRASODIUM ETIDRONATE 0.06 TRIDECETH-2 CARBOXAMIDE MEA 0.85 GLYCEROL 0.5 PHOSPHORIC ACID qs pH 2.2 Water qs 100

Dyeing Protocol

[0385] The dyeing compositions A1, A2 and A3 are each mixed with the oxidizing composition B in a 1+1 weight ratio.

[0386] Each of the mixtures is applied to locks of hair containing 90% natural white (NW) hair and 90% permanent-waved natural white (PW) hair, in a proportion of 5 g of mixture per 1 g of hair.

[0387] After a leave-on time of 30 minutes on a hot plate at 27 C., the hair is rinsed, washed with L'Oral Professionnel Pro Classic universal concentrated shampoo, diluted to 10%, and dried.

Results

[0388] The colouring of the hair is evaluated in the L*a*b* system, using a Konica Minolta CM-3600A spectrocolorimeter (illuminant D65, angle 10, specular component included) in the CIELab system.

[0389] In this system, L* represents the lightness. The lower the value of L*, the darker and more powerful the colouring obtained. The chromaticity is measured by the values a* and b*, a* representing the red/green axis and b* the yellow/blue axis.

[0390] The selectivity is represented by the colour difference E between the locks of dyed natural (NW) hair and dyed permanent-waved (PW) hair, E being obtained from the formula:

E=(L*L.sub.0*).sup.2+(a*a.sub.0*).sup.2+(b*b.sub.0*).sup.2

in which L* represents the intensity and a* and b* represent the chromaticity of the dyed natural hair, and Lo* represents the intensity and a.sub.0* and b.sub.0* represent the chromaticity of the dyed permanent-waved hair. The lower the value of E, the lower the selectivity and the more uniform the colouration along the hair.

TABLE-US-00003 TABLE 3 E A1 + B (invention) 0.53 A2 + B (comparative) 2.70 A3 + B (comparative) 2.69

[0391] The composition according to the invention A1 leads to a lower value of E, and thus to better selectivity, compared to the comparative compositions A2 and A3.
