Keratin is one of structural protein composing our stratum corneum, hair and nail. Specially it comprises 80% of human’s hair. In terms of its amino acid composition, it has cystine which rarely seen in any other kinds of protein. In association with disulfide bond, it has very unique molecular structure that peptide is well cross-linked. Because of this structure, much functional end group such as amino groups and carboxyl groups exist within a single molecule. Consequently, high adsorption can be arose from Keratin. It gives hair strength and body.
Silk is a fiber made of two proteins, mainly fibroin but also sericin. Fibroin has a unique amino acid composition. Glycine, alanine and serine which have small molecular weights and simple chemical structures account for 90%. These amino acids are known to be arranged in β-sheets which greatly contributes to silk well-known shiny appearance and smoothness.
Promois SIG series is a derivative bonded with a silyl group at the N-terminal of the hydrolyzed protien (peptide). It is a "Heat active ingredient", having thermal reactive unique feature, that is different from other peptide derivatives.
Coated layer on the hair surface is formed by the Promois SIG-treatement and heating processes using hair-dryer or hair-iron.
"Heat active effect" , Protecting hair from damages caused by heat and improving the hair strength and texture, is exerted by the layer.

Heat active effect of Promois SIG series
-
Formation of coated layer on the hair surface
Evaluation method:
Damaged hairs treated by Promois SIG were used in this test. Hair surface of test hairs with heating process by hair dryer (65°C, 5min) or without heating process were observed by scanning electron microscope (x 2000).
Control:Damaged hair treated with ion-exchanged water
-
Improvement of smoothness
Evaluation method:
Damaged hairs treated by Promois SIG were used in this test. Smoothness of test hairs with heating process by hair dryer (65°C, 5min) or without heating process were evaluated by friction tester.
Control:
Damaged hair treated with ion-exchanged water.
-
Improvement of hair strength
Evaluation method:
Damaged hairs treated by Promois SIG wre used in this test. Hair strength of test hairs with heating process by hair iron (180°C, 10sec) or without heating process were evaluated by hair rheology analyzer.
Control:
Damaged hair treated with ion-exchanged water.
