Abstract

The present invention relates to a self-molding permanent agent and a method for proceeding free-rod and free-band type permanent, more particularly to a self-molding permanent agent comprising (a) a reducing composition containing a reducing agent reducing a disulfide bond of cystine on the hair and a molding stimulant spontaneously molding to fix a hair design; (b) a molding composition inducing to mold after reacting with the molding stimulant; and (c) a softening composition releasing the action of a molding stimulant, and a method for pressing a free-rod and free-band type permanent, which overcomes a disadvantage in the conventional method for pressing a permanent that needs to wear a curling device such as rods for a permanent (perm rod) or rubber band and improves to apply a wave set without a hair-curling device for a short time, since it has a self-molding feature.
