research Single-cell transcriptomics defines keratinocyte differentiation in avian scutate scales
The research identified two types of keratinocytes in chicken scales: one for hard scales and another for soft skin, with similarities to human skin differentiation.
research Molecular and Cellular Characterization of Avian Reticulate Scales Implies the Evo–Devo Novelty of Skin Appendages in Foot Sole
Bird foot scales develop differently and can repair but not fully regenerate due to the lack of specialized stem cell areas.
research Immunocosmeceuticals: An emerging trend in repairing human hair damage
Immuno-cosmeceuticals from chicken egg yolk can effectively repair and improve damaged hair.
research Development and Evaluation of a Novel Fish-Derived Protein Peptide Conditioner Formulated with Pneumatophorus japonicus Heads Peptides

research Protective Effect of Iris germanica L. Rhizome-Derived Exosome against Oxidative-Stress-Induced Cellular Senescence in Human Epidermal Keratinocytes
Iris germanica rhizome-derived exosomes help protect skin cells from oxidative stress and aging.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research A Raman spectroscopy investigation of the resilience of hair cuticular scales under uniaxial stress
Hair cuticles remain stable and resilient under stress due to strong protein content and crosslinking.
research Repeatable Perming via Thiol–Michael Click Reaction: Using Amide Derived from Maleic Acid and Cystine
A new perming method is less damaging to hair and works as well as traditional methods.
research The Developmental & Molecular Requirements for Ensuring that Human Pluripotent Stem Cell-Derived Hair Follicle Bulge Stem Cells Have Acquired Competence for Hair Follicle Generation Following Transplantation
Scientists found the best time to transplant human stem cells for hair growth is between days 16-18 when they have the right markers and growth potential.
research Natural polymers for natural hair: the smart use of an innovative nanocarrier
Natural polymers can protect, repair, and promote hair regrowth.
research Evolution of hard proteins in the sauropsid integument in relation to the cornification of skin derivatives in amniotes
Hard skin features like scales, feathers, and hair evolved through specific protein changes in different animal groups.
research Structural investigation on damaged hair keratin treated with α,β-unsaturated Michael acceptors used as repairing agents
Treatments improved hair surface and scale structure but didn't increase certain bonds in the hair cortex.
research Hair growth promoting activity of discarded biocomposite keratin extract
Keratin extract from human hair was found to promote hair growth in mice.
