2. Administration of

To prepare ready-to-use pretreatment agent (a), a specified amount of storage reagent (a1) was mixed with a specified amount of reagent (a2) while shaking. Thereafter, the reagent (a) was left to stand for 15 minutes. The reagent (a) is a ready-to-use reagent.

Each strand of hair (Kerling, dark brown) was dipped into the agent (a) and left there for 1 minute. Then, excess product (a) is stripped from each strand of hair. Washing each hair with water. Excess water was scraped from each hair strand.

Immediately thereafter, each hair was immersed in the agent (b) and left for 1 minute. Then, the excess agent (b) is stripped from each strand of hair. Each hair was then thoroughly washed with water (1 minute) and dried.

In examples 1 to 6, very intense and very homogeneous coloration was obtained.

In the case of examples 4, 5 and 6, red-gold bright hair strands were obtained, which were lighter than the dark brown hair used.
