It should be noted that the process is very easy to implement since it is a matter of dissolving the packaging article. It was also observed that the colour obtained is very uniform from the root to the end of the hairs.

(26) The packaging article is prepared in two stages, in a first stage, the powdered ingredients are selected, including the oxidation dyes. The mixture of the powdered ingredients is then homogenized. In a second stage, the envelope is prepared from PVA which are in the form of two nonwoven laps (for invention) or film laps (for comparative) joined together at the periphery, but leaving a part gaping allowing the introduction of ingredients. This double lap is in the form of a disc (5 cm in diameter and 3 mm thick).

(27) The mixture of the said powdered ingredients is then introduced between the two PVA laps of the disc, and the gaping part is then closed.

(28) At the time of treatment each of composition A1 and A2 is mixed with the oxidizing composition B with the weight ratio of 10 parts of composition A1 and A2 for 90 parts of composition B in a bowl until total solubilisation of the ingredients and homogeneity of the mixture. Each mixture A1+B and A2+B is then applied on 90% natural white haire (90 NW) with a bath ratio of 10 g of mixture for 1 g of lock, with a leave-on time of 30 minutes at 27 C. The hair is rinsed and is then shampooed, and the hair is then dried.

(29) Chromaticity C*

(30) The coloration is measured using a Minolta CM 3600 D spectrocolorimeter. The chromaticity is evaluated in the CIE L* a* b* system. In this L* a* b* system, L* represents the intensity of the colour, a* indicates the green/red colour axis and b* indicates the blue/yellow colour axis.

(31) The value of chromaticity C* is calculated from the values of a*b* according to equation (i) below:
C*{square root over (a*.sup.2+b*.sup.2)}(i)

(32) The greater the value of C*, the better the chromaticity of the treated fibres.

(33) Results

(34) The following colorations are obtained:

(35) TABLE-US-00011 Chromaticity a* b* C* A1 + B (comparative) 1.2 0.1 1.2 A2 + B (invention) 2.8 1.6 3.2
The chromaticity of the mixture according to the invention with fibers is significantly higher than that obtained with the film.
