(6) Procedure

(7) At the time of use, 0.828 ml of composition (A), 0.33 ml of composition (B) and 1.242 ml of a composition (C) of 20-volumes aqueous hydrogen peroxide solution are mixed together.

(8) The mixture obtained is applied to 200 mg of locks of natural hair containing 90% white hairs. After a leave-on time of 30 minutes at room temperature, the locks are rinsed and then washed with a standard shampoo.

II. Calculation of the Colour Variation (Eab*)

(9) The coloration build-up (E.sub.ab*) was 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. The lower the value of L*, the darker or more intense the colour.

(10) The value of E.sub.ab* was calculated from the values of L*a*b* according to equation (i) below:
E.sub.ab*={square root over ((L*L.sub.o*).sup.2+(a*a.sub.o*).sup.2(b*b.sub.o*).sup.2)}(i)

(11) The coloration build-up (E.sub.Lab*) was calculated on the locks of untreated hair (L.sub.0*, a.sub.0* and b.sub.0*) and on locks of dyed hair (L*, a* and b*). The values of L.sub.0*, a.sub.0* and b.sub.0* for the untreated natural white hairs are, respectively, 55.56, 2.06 and 12.29.

(12) The greater the value of E.sub.ab*, the better the coverage of the treated fibres.
