be caused depending on the user” (col. 3, lines 19-21). Tsujino
also states that “the method utilizing hydrogen peroxide as the
oxidizing agent is excellent in the dyeing properties, but poor
in the finish of hair” (col. 5, lines 39-42). Hence, Tsujino
indicates that use of hydrogen peroxide produces poor hair
finish, causes hair damage, and may cause skin trouble, but
provides an excellent dyeing effect.
Regarding the use of Tsujino’s enzyme, Tsujino teaches that
“since oxygen in air is activated and utilized, hair damage and
skin trouble are less occurred and also the same dyeing and
bleaching effects as that by the conventional method may be
imparted” (col. 3, lines 22-25). Tsujino also teaches when the
enzyme is used, “a good finish of hair can be obtained while
retaining almost the same dyeing effect as that by using hydrogen
peroxide as the oxidizing agent” (col. 5, lines 43-46). Thus,
Tsujino indicates that use of the enzyme produces good hair
finish, reduces the likelihood of hair damage and skin trouble,
and produces dyeing and bleaching effects which are the same or
almost the same as those obtained using hydrogen peroxide.
