When the spread of the tip of the hair bundle is 8 cm or more and less than 10 cm, it is judged as “good” because a volume feeling is produced. When the spread of the tip of the hair bundle is 6 cm or more and less than 8 cm, it is judged as “possible” because a sense of volume is slightly produced. When the spread at the tip of the hair bundle is less than 6 cm, it is determined as “impossible” because there is no volume feeling.
  • condition was evaluated from the feel when the dyed hair (hair bundle) was touched with a fingertip. Evaluation was performed according to the following criteria. The time when it becomes very smooth is called “excellent”. A smooth time is defined as “good”. When it becomes a little smooth, it is judged as “OK”. When it is not smooth, it is determined as “impossible”.
