<p><P>PROBLEM TO BE SOLVED: To provide a hair modifier and a hair modifying method which can straighten curly hair without giving damage to the hair and the scalp and is suited for increasing the volume of the hair. <P>SOLUTION: The application of a nearly neutral ergothioneine aqueous solution to the hair allows the ergothioneine which takes a thiol structure in an aqueous solution to break into a disulfide bond in the hair to cause replacement reaction and modifies the three-dimensional structure of the hair, and accordingly a curly hair straightening effect can be obtained without affecting peptide bonds. Further, a new disulfide bond is formed in the cysteine residue which does not participate in the disulfide bonds present in the hair. The space in the hair is increased by bonding two zwitterion sites of ergothioneine of the terminal of such a newly formed disulfide in the hair or by bonding the zwitterion site to ergothioneine or an amino acid, and accordingly an increase in the volume of the hair can be achieved. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
