540-570 / 1000+ resultsresearch Extractable substances from human hair: a discussion about the origin of the holes
Holes in mature hair are likely caused by the removal of substances during hair care.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Photodegradation of human hair: a microscopy study
UV radiation significantly damages hair, especially with humidity, making it more vulnerable to further damage.
research Integration Analysis of Transcriptome and Proteome Reveal the Mechanisms of Goat Wool Bending
The research identified key proteins and genes that may influence wool bending in goats.
research Hair-Hair Contact Dynamics and Interactions Studied with Atomic Force Microscopy
Hair movement can indicate hair quality and health.
research Alignment control and softness creation in hair with glycylglycine.
Glycylglycine makes hair softer by improving alignment and changing hair's internal properties.
research Physico-chemical properties of modern cosmetics for styling and their effect on hair structure
Modern hair styling products don't repair hair but improve its surface and stability.
research Effectiveness of blue LED in enhancing hair treatments: Analysis in different hair ethnicities
Blue LED light improves hair treatments for Caucasian and Asian hair but not for African hair.
research Hair-Hair Contact Dynamics and Interactions Studied with Atomic Force Microscopy
Hair movement can indicate hair quality and health.
research In This Issue
Advancements in hair biology include new treatments and tools for hair growth and alopecia.
research Effect of shampoo, conditioner and permanent waving on the molecular structure of human hair
Perming significantly changes hair's molecular structure, while shampoo and conditioner do not.
research Label Retaining Cells (LRCs) with Myoepithelial Characteristic from the Proximal Acinar Region Define Stem Cells in the Sweat Gland
Sweat gland stem cells help maintain glands, aid wound healing, and can regenerate skin structures.
research Comparative genomics analyses of alpha-keratins reveal insights into evolutionary adaptation of marine mammals
Marine mammals lost many α-keratin genes, aiding their adaptation to aquatic life by becoming hairless.
research Side effects after artificial hair implants: 2 case reports
Artificial hair implants can still cause side effects despite improvements.
research Identification of the Keratin-Associated Protein 22-2 Gene in the Capra hircus and Association of Its Variation with Cashmere Traits
A new goat gene affects cashmere fiber thickness; certain variations can make the fibers coarser.
research Human iPS Cell-Derived Cell Aggregates Exhibited Dermal Papilla Cell Properties in in vitro Three-Dimensional Assemblage Mimicking Hair Follicle Structures
Scientists made structures that look like human hair follicles using stem cells, which could help grow hair without using actual human tissue.
research Transcriptome Analysis of Improved Wool Production in Skin-Specific Transgenic Sheep Overexpressing Ovine β-Catenin
Genetically modified sheep with more β-catenin grew more wool without changing the wool's length or thickness.
research Trichorrhexis Nodosa Secondary to Argininosuccinicaciduria
Hair thinning and loss in a girl with a rare metabolic disorder was linked to her condition.
research Shedding light on cashmere goat hair follicle biology: from morphology analyses to transcriptomic landascape
The research found genes that change during cashmere goat hair growth and could help determine the best time to harvest cashmere.
research Keratin Gene Expression in Wool Fibre Development
Only two of the four keratin genes are expressed in wool fibers.
research Polymorphism of Keratin Gene KRT71 and Its Relationship with Wool Properties in Gansu Alpine Fine-Wool Sheep
The GG genotype of the KRT71 gene leads to longer wool in Gansu alpine fine-wool sheep.
research Micro‐RNA‐31 controls hair cycle‐associated changes in gene expression programs of the skin and hair follicle
miR-31 regulates hair growth by controlling gene expression in hair follicles.
research Structural Hierarchy of Trichocyte Keratin Intermediate Filaments
Keratin proteins are crucial for hair growth and structure.
research Cryopreservation of Hair-Follicle Associated Pluripotent (HAP) Stem Cells Maintains Differentiation and Hair-Growth Potential
Freezing and storing special stem cells from hair follicles keeps their ability to grow hair and turn into different cell types.
research Unexpected Autocrine Role of Vascular Endothelial Growth Factor in Squamous Cell Carcinoma
VEGF helps squamous cell carcinoma grow in ways beyond just blood vessel formation.
research The structure of people’s hair
Hair's molecular structure is mostly consistent, but genetic differences affect lipid types, which could help diagnose diseases.
research Deletion of hypoxia-inducible factor prolyl 4-hydroxylase 2 in FoxD1-lineage mesenchymal cells leads to congenital truncal alopecia
Removing a specific gene in certain skin cells causes hair loss on the body by disrupting normal hair development.
research Pitx2, a β-catenin-regulated transcription factor, regulates the differentiation of outer root sheath cells cultured in vitro
