Zusammenfassung: | PROBLEM TO BE SOLVED: To allow inexperienced technicians to find hair softening and hair damage as well as skilled technicians who only can find hair softening and hair damage through their experiences such as touching the hair with their hands. SOLUTION: The softened or damaged hair becomes elastic like rubber after a chemical is applied to the hair or when the hair is wet. Main bodies A1, A2 are assembled, and the hair is pinched by each hair catching part 3 of the main bodies A1, A2 not to make the hair go slack. The inexperienced technician can distinguish the state of hair softening and hair damage easily since the length of the hair stretched or shrunk by repulsive force of an elastic material 4 is an indication of hair softening or hair damage. |
