EXAMPLES OF DYEING

Example 1

[0377] The following compositions are prepared from the following ingredients in the following proportions, indicated in grams per 100 grams of composition:

Dyeing Composition:

[0378]

TABLE-US-00001 Composition 1 Amount Extract of logwood containing 76% haematoxylin: a)   4 g Dihydroxybis(ammonium lactato)titanium(IV) at 50% by weight: b) 10.3 g Scleroglucan gum (sclerotium gum) sold by Alban   1 g Muller under the trade name Amigal Granule: c) Ethanol   10 g Benzyl alcohol   5 g Glycolic acid   15 g Water qs  100 g pH agent (sulfuric acid) qs pH = 2 ± 0.3

Developing Composition:

[0379]

TABLE-US-00002 Composition B Amount Aqueous hydrogen peroxide solution (50%): d)  1.7 g Sodium bicarbonate: e)    5 g L-Arginine: e)    7 g Hydroxypropyl starch phosphate sold under the name    5 g Structure Zea by Akzo Nobel Water qs  100 g pH agent (sodium hydroxide) pH 10.2 ± 0.3
Dye composition 1 and then composition B are applied with a brush to the following types of hair: [0380] natural and permanent-waved Caucasian hair containing 90% white hairs, [0381] natural Chinese hair containing 100% white hairs.
Composition 1 is then left in place for a time of 45 minutes at 40° C. and composition B is left in place for 15 minutes at 40° C. Rinsing is performed before applying composition B.
After these leave-on times, the locks are washed with Elvive multivitamin shampoo, rinsed and then dried under a hood.

Dyeing Results

[0382] 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.

[0383] 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:

[0384] The variation in colouring between the locks of natural 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.o*).sup.2+(a*−a.sub.o*).sup.2+(b*−b.sub.o*).sup.2)}

[0385] 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.

[0386] The results L, a, b of colour build-up are collated in the table below:

TABLE-US-00003 ΔE* Types of hair and treatment Colour L* a* b* build-up Undyed reference hair Natural Caucasian, 90% — 68.92 1.64 20.44 — white Natural Chinese, 100% white — 79.33 2.65 28.19 — Composition 1 then B Natural Caucasian, 90% Black 20.47 0.63 1.04 52.20 white Natural Chinese, 100% white Black 22.74 0.9 0.91 62.85
