Hair growth and hair restoration material

Abstract

Provided is a novel hair growth and hair restoration material having excellent efficacy in hair growth and hair restoration for both men and women, even when the components thereof are at ultra-dilute concentrations; the hair growth and hair restoration material being characterized in containing a steryl glucopyranoside, preferably a cholesteryl glucopyranoside, represented by general formula (I). (In the formula, Z represents a sterol residue from which the hydroxyl group attached to the 3-position of a cyclopentanohydrophenanthrene ring has been removed.)

1 . A hair growth and hair restoration material characterized by comprising a steryl glucopyranoside represented by general formula (I): 
       
         
           
           
               
               
           
         
         (wherein Z represents a sterol residue from which the hydroxyl group attached to the 3-position of a cyclopentanohydrophenanthrene ring has been removed.) 
       
     
     
         2 . The hair growth and hair restoration material according to  claim 1 , characterized in that the sterol residue in the general formula (I) is a cholesterol residue, a β-sitosterol residue, a stigmasterol residue, a campesterol residue, or a brassicasterol residue. 
     
     
         3 . The hair growth and hair restoration material according to  claim 2 , characterized in that the steryl glucopyranoside is a cholesteryl glucopyranoside. 
     
     
         4 . The hair growth and hair restoration material according to  claim 1 , characterized in that the steryl glucopyranoside is a naturally occurring substance and/or a synthetic product. 
     
     
         5 . The hair growth and hair restoration material according to  claim 3 , characterized in that characterized in that the steryl glucopyranoside is obtained from bird feathers. 
     
     
         6 . The hair growth and hair restoration material according to  claim 2 , characterized in that the steryl glucopyranoside is a naturally occurring substance and/or a synthetic product. 
     
     
         7 . The hair growth and hair restoration material according to  claim 3 , characterized in that the steryl glucopyranoside is a naturally occurring substance and/or a synthetic product.
