Locks of the Following Types of Hair:

[0352] natural and permanent-waved Caucasian hair containing 90% white hairs, and [0353] natural Chinese hair containing 100% white hairs, are successively treated with: [0354] composition 1 or 2, which is left to stand on the locks for 45 minutes at 40° C. and then rinsed out, [0355] composition B, which is then left to stand on the locks for 15 minutes at 40° C.

[0356] After these leave-on times, the locks are washed with Elvive multivitamin shampoo, rinsed and then dried under a hood.

Dyeing Results

[0357] It is found that very strongly coloured black locks are obtained, which is corroborated by the colorimetric measurements below. In addition, it is seen that the colouring is visually homogeneous and persistent with respect to successive shampooing.

[0358] The colour of the locks was evaluated in the CIE L* a* b* system using a Minolta Spectrophotometer CM3600D colorimeter. In this L* a* b* system, the three parameters denote, respectively, the colour intensity (L*), the green/red colour axis (a*) and the blue/yellow colour axis (b*).

Colour Build-Up:

[0359] The variation in colouring between the locks of natural or permanent-waved hair comprising 90% white hairs or of Chinese hair containing 100% white hairs before and after treatment or dyeing are defined by (ΔE*) according to the following equation:

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

[0360] In this equation, L*, a* and b* represent the values measured on locks of hair after dyeing and L.sub.0*, a.sub.0* and b.sub.0* represent the values measured on locks of undyed virgin hair. The higher the ΔE* value, the better the colour build-up.

[0361] The results L, a, b of colour build-up are collated in the table below:

TABLE-US-00003 DE* Hair Colour L* a* b* build-up Untreated reference hair Natural Caucasian 90% white — 66.88 0.96 16.34 — Permanent-waved natural — 65.99 0.57 15.03 — Caucasian 90% white Natural Chinese 100% white — 77.69 1.85 23.38 — Composition 1 followed by B Natural Caucasian 90% white Black 20.44 0.38 −0.76 49.5 Permanent-waved natural Black 19.8 0.31 0.43 48.44 Caucasian 90% white Natural Chinese 100% white Black 22.8 0.11 −1.53 60.3 Composition 2 followed by B Natural Caucasian 90% white Black 19.75 0.31 −0.19 49.95 Permanent-waved natural Black 20.37 0.32 0.65 47.83 Caucasian 90% white Natural Chinese 100% white Black 21.29 1.06 0.6 60.83

[0364] After these leave-on times, the locks are washed with Elvive multivitamin shampoo, rinsed and then dried under a hood.

[0365] The locks treated with the compositions 3 and B are a very strong and intense black.
