[0368] Dyeing Protocol

[0369] The dyeing compositions A, A1 and A2 are each mixed with the oxidizing composition B in a 1+1 weight ratio.

[0370] Each of the mixtures is applied to locks of hair containing 90% natural white (NW) hair in a proportion of 5 g of mixture per 1 g of hair.

[0371] After a leave-on time of 30 minutes on a hot plate at 27 C., the hair is rinsed, washed with L'Ore{right arrow over (a)}l Professionnel Pro Classic universal concentrated shampoo, diluted to 10%, and dried.

[0372] Results

[0373] 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.

[0374] 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.

[0381] Dyeing Protocol

[0382] The dyeing compositions A, A, A1 and A1 are each mixed with the oxidizing composition B in a 1+1 weight ratio.

[0383] Each of the mixtures is applied to locks of hair containing 90% natural white (NW) hair and permanent-waved hair (PW), in a proportion of 5 g of mixture per 1 g of hair.

[0384] 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.

[0385] Results

[0386] 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.

[0387] 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.

[0388] 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={square root over ((L*L.sub.0*).sup.2+(a*a.sub.0*).sup.2+(b*b.sub.0*).sup.2)} [0389] 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 E, the lower the selectivity and the more uniform the colouration along the hair.

[0390] The following results are obtained.

[0391] Composition A according to the invention leads to a lower value of E, and thus to better selectivity, compared to comparative composition A1. The coloration along the lock of hair is more homogenous with A+B.
