research An ultrastuctural study of hair fiber damage and restoration following treatment with permanent hair dye
Permanent hair dye damages hair but it mostly recovers after 8 weeks; using certain hair care products can help repair it.
research The hair cycle and its regulation
Hormones, nutrition, and seasonal changes regulate hair growth cycles, with androgens extending growth phases and factors like aging and malnutrition affecting hair loss and thinning.
research Trichoscopy in Hair Shaft Disorders
Trichoscopy is a useful tool for diagnosing hair disorders without pulling out hair.
research Integral hair lipid in human hair follicle
Human hair has a protective lipid layer that can be damaged by moisture and treatments, affecting hair growth and health.
research Characterization and Chromosomal Localization of Human Hair-Specific Keratin Genes and Comparative Expression During the Hair Growth Cycle
Two specific hair keratin genes are active during hair growth and decline as hair transitions to rest.
research Beyond goosebumps: Does the arrector pili muscle have a role in hair loss?
The arrector pili muscle might play a role in hair loss and needs more research to understand its impact.
research Bulge cells of human hair follicles: segregation, cultivation and properties
Researchers found that bulge cells from human hair can grow quickly in culture and have properties of hair follicle stem cells, which could be useful for skin treatments.
research Size Polymorphisms in the Human Ultrahigh Sulfur Hair Keratin-Associated Protein 4, KAP4, Gene Family
The study found that variations in hair protein genes are likely due to evolutionary deletions or duplications.
research Raman spectroscopy and electronic microscopy structural studies of Caucasian and Afro human hair
Hair treatments cause significant structural changes, especially with excessive heat, regardless of ethnicity.
research Large-scale cultivation of transplantable dermal papilla cellular aggregates using microfabricated PDMS arrays
Researchers developed a method to grow hair follicle cells for transplantation using a special chip.
research Isolation and Characterization of a Novel Hair Follicle–Specific Gene, Hacl-1
Researchers found a new gene, hacl-1, that is active in mouse hair follicles during hair growth and may be important for hair biology.
research Preclinical studies of a novel polyherbal phyto–complex hair growth promoting cream
The herbal cream was found to be a safe and effective alternative for hair growth, similar to minoxidil.
research Insights on the mechanical behavior of keratin fibrils
Keratin's mechanical properties are influenced by hydrogen bonds and secondary structure, and can be improved with the SPD-2 peptide.
research Diseases on Hair Follicles Leading to Hair Loss Part I: Nonscarring Alopecias
Common types of non-scarring hair loss have various causes and treatments, but more effective solutions are needed.
research Immunocytochemical Localization of Androgen Receptors in the Scalp of the Stumptail Macaque Monkey, a Model of Androgenetic Alopecia
Androgen receptors found in monkey scalps, similar to humans, affect hair growth.
research Environmental and Cosmetic Factors in Hair Loss and Destruction
Environmental and cosmetic factors, including heat, chemicals, and sun exposure, can cause hair loss and damage.
research Characterization of hair lipid images by argon sputter etching-scanning electron microscopy
Hair texture changes with age due to varying levels of lipids.
research Transcriptomic inspection revealed a possible pathway regulating the formation of the high-quality brush hair in Chinese Haimen goat ( Capra hircus )
Scientists found genes linked to the growth of high-quality brush hair in Chinese Haimen goats.
research Keratin 71 Mutations: From Water Dogs to Woolly Hair
A mutation in the KRT71 gene causes a hair disorder by disrupting hair follicle structure and texture.
research A case of patchy alopecia areata sparing lesional greying hairs
Greying hairs may be protected from alopecia areata.
research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research A highly resistant structure between cuticle and cortex of human hair
A tough membrane between the outer and inner layers of human hair protects it from damage.
research Hair keratin film as a substitute device for human hair
Keratin film can effectively replace human hair for testing hair damage.
research The Critical Roles of Serum/Glucocorticoid-Regulated Kinase 3 (SGK3) in the Hair Follicle Morphogenesis and Homeostasis
SGK3 is essential for proper hair growth and health.
research Mechanism of Cuticle Hole Development in Human Hair Due to UV-Radiation Exposure
UV radiation damages hair by creating holes and peeling cuticle layers.
research Kinetics and Equilibrium of Solute Diffusion into Human Hair
Hair absorbs molecules differently based on their size, charge, and love for water, and less at higher pH; this can help make better hair products.
research Preparation of Water Soluble Wool Keratin and Its Application for Human Hair
Water-soluble wool keratin can protect human hair from damage during treatments.
research Keratin-mediated hair growth and its underlying biological mechanism
Keratin injections can promote hair growth by affecting hair-forming cells and tissue development.
research External lipid function in ethnic hairs
African hair has the most lipids, while Caucasian hair is more hydrated and stronger.
