<p>This invention provides a method for altering hairs by bringing the hairs into contact with an elastic body vibrating ultrasonically. At first, the alternate vibrations are generated on a rod portion (a cylindrical elastic body). The cylindrical shaped elastic body does not rotate at that time. However, when one object is in contact with the surface of the cylindrical shaped elastic body, the object is rotated. Further when the object is kept stationary, the object is squeezed by spiral vibrations. In case that the hairs are in contact with the circumferential surface of the cylindrical shaped elastic body, the contacting part of the hairs are squeezed in the circumferential direction by the vibrations of the cylindrical shaped elastic body. Whereby, the cross-section of each hair is deformed then the deformation of each hair is remained. Thus, the perming is carried on. <IMAGE></p> |
