[0393] Oxidizing Composition

[0394] The oxidizing composition B was prepared from the ingredients of which the contents are indicated in the table below:

TABLE-US-00002 TABLE 2 B HYDROGEN PEROXIDE 6 CETEARYL ALCOHOL 6 STEARETH-20 5 PEG-4 RAPESEEDAMIDE 1.3 TETRASODIUM ETIDRONATE 0.2 TETRASODIUM PYROPHOSPHATE 0.04 SODIUM SALICYLATE 0.035 PARAFFINUM LIQUIDUM 20 POLYQUATERNIUM-6 0.5 GLYCEROL 0.5 HEXADIMETHRINE CHLORIDE 0.25 TOCOPHEROL 0.1 PHOSPHORIC ACID qs pH 2.2 Water qs 100

[0395] Dyeing Protocol

[0396] The dyeing compositions A1 and A2 are each mixed with the oxidizing composition B in a 1+1 weight ratio.

[0397] 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.

[0398] After a leave-on time of 30 minutes on a hot plate at 27 C., the hair is rinsed, washed with L'Oreal Professionnel Pro Classic universal concentrated shampoo, diluted to 10%, and dried.

[0399] Results

[0400] 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.

[0401] 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.

[0402] The selectivity is represented by the colour difference AE between the locks of dyed natural (NW) hair and dyed permanent-waved (PW) hair, AE being obtained from the formula:

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

[0403] in which L* represents the intensity and a* and b* represent the chromaticity of the dyed natural hair, and L.sub.0* 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 AE, 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) 2.98

[0404] The composition according to the invention A1 leads to a lower value of E, and thus to better selectivity, compared to the comparative composition A2.
