2. Application

[0454] To prepare the pre-treatment agent (a) ready for use, the indicated quantity of the stored agent (a1) was mixed with the indicated quantity of the agent (a2) while shaking. Afterwards the agent (a) was left to stand for 15 minutes. The agent (a) is the ready-to-use agent.

[0455] One strand of hair each (Kerling, dark brown) was dipped into the agent (a) and left there for 1 minute. Afterwards, excess product (a) was stripped from each strand of hair. Each strand of hair was washed out with water. Excess water was scraped off each strand of hair.

[0456] Immediately afterwards, the hair strands were each dipped into the agent (b) and left in it for 1 minute. Afterwards, excess agent (b) was stripped from each strand of hair. Then each strand of hair was washed thoroughly (1 minute) with water and dried.
