Dyeing Protocol

[0363] The dyeing compositions A and C are each mixed with the oxidizing composition B in a 1+1 weight ratio.

[0364] Each of the mixtures is applied to locks of permanent-waved hair containing 90% of grey hair in a proportion of 5 g of mixture per 1 g of hair.

[0365] After a leave-on time of 35 minutes on a hot plate at 27 C., the hair is rinsed, washed with a standard shampoo and dried.

Results

[0366] 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.

[0367] In this system, L* represents the lightness. The lower the value of L*, the darker and more powerful the colouring obtained.

[0368] The results are given in the table below:

TABLE-US-00003 TABLE 3 L* A + B (invention) 21.5 C + B (comparative) 23.7

[0369] Composition A according to the invention leads to a lower value of L*, thus to a better colour strength, compared to the comparative composition C.

Oxidizing Composition

[0371] Oxidizing composition B1 is an aqueous solution comprising 6% of hydrogen peroxide.

Dyeing Protocol

[0372] The dyeing compositions A1 and C1 are each mixed with the oxidizing composition B1 in a 1+1 weight ratio.

[0373] Each of the mixtures is applied to locks of natural hair containing 90% of grey hair in a proportion of 5 g of mixture per 1 g of hair.

[0374] After a leave-on time of 35 minutes at 25 C., the hair is rinsed, washed with a standard shampoo and dried.

Results

[0375] 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.

[0376] In this system, L* represents the lightness. The lower the value of L*, the darker and more powerful the colouring obtained. The chromaticity C* is calculated from the values a* and b*, a* representing the red/green axis and b* the yellow/blue axis.

[00001]$C^{*}=\sqrt{{\left(a^{*}\right)}^2+{\left(b^{*}\right)}^2}$

[0377] The higher the value of C*, the better the chromaticity.

[0378] The results are given in the table below:

[0379] Composition A1 according to the invention leads to a higher value of C*, thus to a better chromaticity, compared to the comparative composition C1.
