摘要:
A method for acquiring hair characteristic data includes an image acquiring step and a data acquiring step. The image acquiring step acquires a cross-sectional image of a human hair 50, in which plural types of fibrous tissues (ortho cell 52a, para cell 52b) constituting cortex cells 52 contained in the human hair 50 are visualized so as to be distinguishable from each other. The data acquiring step acquires numerical information indicating a distribution state of the visualized plural types of fibrous tissues (ortho cell 52a, para cell 52b) from the cross-sectional image.

摘要:
The invention relates to a hair treatment composition comprising (a) a guanidium salt, (b) an alkalizing agent other than the guanidium salt and (c) a silicone. The use of the hair treatment composition permits brightening the color tone of the hair or dyeing the hair in good shades from a bright shade to a deep shade. The composition scarcely damages the hair, gives off little irritating odor and has low irritativeness to the scalp.
摘要:
The object of the invention is a composition for permanent waving of human hair comprising, as sole or main reducing agent one or several polyglycol monothioglycollates or lactates of the general formula ##STR1## wherein R denotes a hydrogen atom or a methyl group, X represents an ethoxy or propoxy group, and n is a number from 2 to 5. These compositions have a low characteristic smell, good waving properties, and an extremely low skin sensitizing potential.
摘要:
A relation equation between wave information on unpermed hair strands and evaluation values of appearance of whole hair selected from among gloss of the whole hair, order of alignment of the hair strands, and frizziness of the hair strand is acquired from a plurality of subjects. Based on the relation equation, the appearance of whole hair of an arbitrary subject is evaluated from wave information on a hair strand of the arbitrary subject. This allows an objective evaluation of the gloss of whole hair, the order of alignment of hair strands, or the frizziness of the hair strand by a simple technique, and also allows an objective evaluation corresponding to cosmetic specialists' evaluations in terms of equivalent age.
摘要:
Provided is a hair frizziness reducing agent containing a lower alcohol and water, having a viscosity of from 1 to 90,000 mPa·s and used by leaving, after application to the scalp, the agent as is without washing it away.
摘要:
The object of the invention is a new isomer mixture of 3-hydroxybutyl monothioglycollate and 3-hydroxy-1-methyl propyl monothioglycollate in a weight proportion of about 1.5:1 to 4:1, preferably about 2:1 to about 3:1, comprising less than 5%, preferably less than 2% by wt., of 1,3-butanediol thioglycollate, and its use as the sole or main reducing agent in compositions for permanent waving of human hair. The compositions have reduced smell, good waving properties and an extremely low sensitizing potential on human skin.

摘要:
This invention relates a hair cosmetic composition, which comprises (A) glycine or alanine, (B) an &agr;-hydroxy acid, &bgr;-hydroxy acid, 1,2-dicarboxylic acid, 1,3-dicarboxylic acid or aromatic carboxylic acid, and (C) a cationic surfactant. The hair cosmetic composition is excellent in the effect of improving optical or mechanical properties of hair.
摘要:
This invention relates to a hair cleansing composition, which comprises (A) 0.01 to 20 wt. % of glycine or alanine, (B) 0.01 to 5 wt. % of an &agr;-hydroxy acid, &bgr;-hydroxy acid, 1,2-dicarboxylic acid, 1,3-dicarboxylic acid or aromatic carboxylic acid, and (C) 5 to 40 wt. % of an anionic surfactant selected from an alkylsulfuric acid salt, an alkylethersulfuric acid salt or an N-alkylamidoalkanolsulfuric acid ester salt. The hair cleansing composition is excellent in the effect of improving optical or mechanical properties of hair.
