○ (Good): Almost no color transfer to the filter paper is observed △ (Slightly good): Color transfer to the filter paper is observed, but the color is lighter than the color of the hair bundle × (Poor): Color transfer to the filter paper is observed can be seen and is at the same level as the color applied to the hair tress

(Test Example 4: Color transfer after hair coloring)
After the hair tresses that had been styled in Test Example 2 were allowed to stand for 10 minutes, the tresses were sandwiched between filter papers. After a 1 L beaker was placed on the filter paper to make it 1 kg by adding water, the hair tress was immediately pulled out from the filter paper. Color transfer after coloring the hair was visually evaluated according to the following evaluation criteria.
