20 / 972 resultsresearch Final Report on the Safety Assessment of Human and Animal Placental and Umbilical Extracts in Cosmetics
This review discusses the use of human and animal-derived placental and umbilical extracts in cosmetics, highlighting insufficient data to establish their safety and recommending they should not have metabolic or endocrine activity.
research Comparison of Hair Shaft Repairing Efficacy Between Panthenol and Hydrolyzed Protein
Panthenol is more effective than hydrolyzed protein at improving hair roughness and reducing breakage.
research Placental Extracts, Proteins, and Hydrolyzed Proteins as Active Ingredients in Cosmetic Preparations for Hair Loss: A Systematic Review of Available Clinical Evidence
This study suggests that while some evidence indicates potential efficacy of placental products for hair growth and inhibiting hair loss, the current scientific evidence is scarce and of low quality.
research Investigations on the Penetration of Hydrolyzed Wheat Proteins into Human Hair by Confocal Laser-Scanning Fluorescence Microscopy
This study found that hydrolyzed wheat proteins extensively penetrated both untreated and chemically treated hair, primarily occupying areas like the endocuticle and cortex.
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 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 An Ex Vivo Comparative Study of the Tensile Strengthening Efficacy of Protein-Derived Actives on Heavily Bleached Hair
This study compared hydrolysed wheat protein, L-arginine, and hydrolysed collagen for their effectiveness in enhancing the tensile strength of heavily bleached hair.
research Evaluation of a Novel Hybrid Polymer in Hair Treatment
This study found that a new hybrid polymer made from hydrolyzed protein, alkyl chain, and silicone helped prevent discoloration and improve moisture feel and manageability in dyed and damaged hair.
research Evaluation of a Novel Hybrid Polymer in Hair Treatment
This study found that a new hybrid polymer containing hydrolyzed protein and silicone effectively improved moisture feel and prevented discoloration in dyed hair, particularly benefiting damaged hair.
research Abstracts
This review discusses autoimmune blistering diseases across species and highlights new treatment efficacy findings and ongoing trials, but it reports no new clinical results.
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 Protective Effect of Conditioner Agents on Hair Treated with Oxidative Hair Dye
This study found that conditioner agents reduced the damage caused by oxidative hair dye, specifically improving protein retention and combability in treated Caucasian hair.
research Formulation and Evaluation of Herbal Hair Gel
This study found that an herbal hair gel formulated with natural ingredients like aloe vera and essential oils showed stability, effectiveness, and aesthetic appeal, suggesting it could be a viable, safe alternative to synthetic hair gels, with potential for future production and clinical evaluation.
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 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 Evaluation of the Active Ingredient Complex of an Anti-Hair Loss Shampoo on the Activation of Wnt/β-Catenin Pathway in Human Hair Follicle Dermal Papilla Cells
This study reported that an anti-hair loss shampoo containing six active ingredients activated the Wnt/β-catenin pathway in human hair follicle dermal papilla cells in vitro.
research Evaluation of Anti-Hair Loss Shampoo Through In Vitro Activity in Human Hair Follicle Dermal Papilla Cells and Sensorial Study
This study found that a shampoo containing a 6-active ingredient complex increased β-Catenin production in human hair follicle dermal papilla cells to levels comparable to Finasteride, suggesting potential for promoting hair growth. It also showed good cleaning efficacy, volume, and shine in a sensorial study.
research Evaluation of Hair Damage Treated With Oxidative Hair Dye Under Influence of Conditioner Agents
In this study, adding conditioning agents PA1, PA2, and PA3 to light blonde oxidative hair dyes improved combability and protein retention of light brown hair without affecting tensile strength, though PA1 and PA2 offered enhanced thermal protection.
research Transparent Silicone-Free Shampoo Containing Proteins With Strong Hair Conditioning Properties
The researchers reported that adding specific combinations of hydrolyzed proteins to silicone-free shampoo improved hair conditioning properties by reducing friction and increasing surface adsorption and penetration into hair, compared to protein-free alternatives.
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.
