<P>PROBLEM TO BE SOLVED: To provide a permanent wave second agent having small loads on hair, usable continuously and repeatedly in a short period, and not imposing a burden on an environment. <P>SOLUTION: Water containing nanobubbles containing oxygen wherein the most frequent value of bubble diameters is ≤250 nm is used as a permanent wave second agent, in succession with a step for treating hair by a reducing agent. In a step for treating hair by nanobubble water, hair may be subjected to immersion treatment in nanobubble water, or the hair may be treated by a stream of nanobubble water. <P>COPYRIGHT: (C)2013,JPO&INPIT |
