2. Administration of

A lock of hair (Kerling, natural hair white in europe) was dipped into the agent (a) and left there for 1 minute. Thereafter, excess agent (a) is removed from each lock of hair. Each lock of hair was briefly washed with water. Excess water is wiped from each lock of hair.

Subsequently, the tresses were each immersed in the agent (b) and left there for 1 minute. Thereafter, excess agent (b) is removed from each lock of hair. Each lock of hair was briefly washed with water. Excess water is wiped from each lock of hair.

The locks are then individually wetted with a small amount of reagent (c). The reagent (c) was allowed to act for 1 minute. The tresses are then rinsed with water and wiped dry. Subsequently, the tresses were evaluated visually.
