20 / 913 resultsresearch Penetration of Different Molecular Weight Hydrolysed Keratins into Hair Fibres and Their Effects on the Physical Properties of Textured Hair
This study investigated the effects of wool-derived hydrolysed keratin peptides on relaxed textured hair and found that mid- and high-molecular weight peptides improved mechanical strength and reduced breakage in different humidity conditions.
research Keraglo Hydrolyzed Keratin: A Healthy Aging Supplement, Improved Skin And Hair In A Placebo Controlled Trial
In this study, hydrolyzed keratin supplementation using KeraGLO® significantly improved skin parameters such as wrinkle depth, smoothness, moisture, and firmness, as well as hair health, in healthy adult females over a 90-day period at both 500mg and 1000mg doses.
research Effects of Hydrolyzed Keratin Treatment on the Repair of Damaged Hair
This study found that the newly developed hair product K-30 increased both protein content and weight in chemically damaged hair to levels similar to healthy hair, unlike traditional products that only temporarily improve texture.
research Hydrolyzed Keratin Peptide Enhances Hair Condition And Promotes Hair Regeneration
This study found that orally administered hydrolyzed keratin peptide promoted hair growth and enhanced cellular proliferation and antioxidant capacity in mice and human cell models, suggesting its potential as a functional food ingredient for hair health.
research Extraction and Formulation of Hydrolyzed Wool Keratin Solution for Hair Growth
In this study, topical application of keratin extract from wool promoted hair growth in mice by reducing the time for initiation and completion of growth phases and improving hair quality.

research Raman Spectroscopic Analysis of L-Phenylalanine and Hydrolyzed Eggwhite Protein Penetration into Keratin Fibers
This study found that hydrophobic amino acids from egg white hydrolyzed protein and L-phenylalanine effectively penetrate deep into the human hair fiber, increasing specific contents in both virgin and bleached hair.
research Development of a Novel Penetration-Enhancing Agent for Hair Products
This study found that the new HCC additive enhances the permeation of pigments and active ingredients into hair, suggesting potential use in developing functional cosmetic hair products.
research Thin Hair
This abstract highlights that maintaining healthy, voluminous thin hair involves using gentle care products, such as shampoos, conditioners, and masks containing specific ingredients like hydrolyzed keratin, collagen, and panthenol, to improve manageability, strength, and moisture retention.
research Evaluation of the Efficacy of a Food Supplement on Subjects with Acute Telogen Effluvium
The food supplement may help reduce hair shedding and improve hair growth.
research Interaction of Polypeptides with Hair in Different Reducing Environments
This study found that different polypeptides, including KP peptide and hydrolyzed keratin, can improve the mechanical properties of damaged hair under varying conditions, with reduction environments and cysteine content influencing their effectiveness.
research Artemisia Argyi Ameliorates Nonalcoholic Steatohepatitis by Modulating Fibrosis-Related Factors and Gut Microbiota
In this study, KeraGLO, a nutritional supplement with hydrolyzed keratin, was shown to significantly improve skin wrinkle depth, smoothness, moisture, firmness, and hair health in healthy adult females over a 90-day period at both 500mg and 1000mg doses compared to baseline.
research Direct Observation of Hair Components Involved in Formation of Permanent Waves
This study found that microfibrils play a crucial role in shaping permanent waves by thioglycolic acid, and treating damaged hair with hydrolyzed keratin improved both waving efficiency and hair damage.
research Can Hair Be Protected From Oxidative Damage During and After Bleaching
This study assessed three materials—L-arginine, hydrolysed keratin, and cystine-silanol copolymer—ex vivo for their potential to reduce undesirable effects of hair bleaching, such as damage to hair proteins.
research Amino Acids, Peptides, And Proteins In Cosmetic Science
This review focuses on the roles of amino acids, peptides, and proteins in cosmetics, highlighting their importance in skin health and their potential for development in personal care products due to their unique properties and biocompatibility.
research Internal Structure Changes in Bleached Black Human Hair Resulting from Chemical Treatments: A Raman Spectroscopic Investigation
In this study, the authors concluded that a hydrolyzed eggwhite protein treatment promoted the reconnection of disulfide bonds in excessively bleached hair, after reduction and oxidation processes in permanent waving.
research Nutrients Regulation of Skin Cells From Canines and Cats Via Wnt/β-Catenin Signaling Pathway
This study found that keratin hydrolyzed, egg yolk lecithin, and fish collagen peptide promoted β-catenin nuclear translocation and increased gene expression related to hair regeneration in canine and cat skin cell lines, suggesting these nutrients may help improve hair regeneration in pets.
research Enzymatic Crosslinking of Amino Acids Improves the Repair Effect of Keratin on Hair Fiber
This study found that a bio-based repair solution containing hydrolysed wool keratin, serine, and transglutaminase improved the physical and chemical properties of damaged hair, increasing its strength, flexibility, and thermal stability while offering long-lasting protection against chemical damage.
research Morphological and Biochemical Investigations of Hair in Disturbed Amino Acid Metabolism
Metabolic disorders can cause hair structure defects and growth issues, but amino acid levels in hair remain normal.
research Efficacy and Safety of L-Cystine Associated or Not to a Natural Keratin (Kera-Diet) Hydrolysate on Hair and Nails: Randomized, Placebo-Controlled, Clinical Trial on Healthy Females
In this study, researchers found that supplementation with L-cystine, either alone or with a keratin hydrolysate, significantly improved hair density, hair and nail brightness, and nail growth in women experiencing acute telogen effluvium and brittle nail syndrome over three months.
