840-870 / 1000+ results research K25 (K25irs1), K26 (K25irs2), K27 (K25irs3), and K28 (K25irs4) Represent the Type I Inner Root Sheath Keratins of the Human Hair Follicle
K25, K27, and K28 are found in all inner root sheath layers of hair, while K26 is only in the cuticle.
research Dynamic ultrastructural changes of the connective tissue sheath of human hair follicles during hair cycle
The connective tissue around hair follicles changes structure throughout the hair cycle.
research Effects of sulfated fucans on the growth cycle of murine hair follicles
Sulfated fucans promote hair growth in mice by speeding up the growth phase and delaying the rest phase.
research Plucked Human Hair Shafts and Biomolecular Medical Research
Human hair follicles may provide a noninvasive way to diagnose diseases and have potential in regenerative medicine.
research Hair resistance to mechanical wear
Hair's resistance to wear varies by ethnicity and treatment, with less wear indicating stronger hair.
research Hox in the Niche Controls Hairy-geneity
Hox genes control hair growth patterns in mammals by regulating stem cell activity in the skin.
research Immune cell regulation of the hair cycle
Immune cells affect hair growth and could lead to new hair loss treatments.
research TYPICAL MORPHOLOGICAL CHARACTERISTICS OF THE SKIN STRUCTURE OF THE HAIR PART OF THE NORMAL HUMAN HEAD AND WITH HAIR LOSS
Androgenic alopecia causes hair follicle degradation and skin restructuring, but some hair elements remain.
research Multipotent nestin-positive, keratin-negative hair-follicle bulge stem cells can form neurons
Hair-follicle stem cells can become neurons.
research Disorders of Hair
Hair disorders are complex and varied, including hair loss, excessive growth, color, and shaft issues.
research Lanceolate Hair (lah): A Recessive Mouse Mutation with Alopecia and Abnormal Hair
Mice with the 'lanceolate hair' mutation have abnormal hair and skin similar to human Netherton's syndrome.
research Influence of the hair growth cycle on the glyceride content of whole mouse skin
Glyceride levels in mouse skin are higher during hair growth.
research Mapping of cis-acting expression quantitative trait loci in human scalp hair follicles
Researchers identified genes in scalp hair follicles that may affect hair traits and hair loss.
research Hair Counts from Normal Scalp Biopsy in Taiwan
The conclusion is that normal scalp hair counts for Taiwanese people were established, showing age-related differences but not sex or scalp location differences.
research New Aspects of the Structure of Human Scalp Hair-II: Tubular Structure and Material Flow Property of the Medulla.
The medulla in Asian scalp hair has a tubular structure that allows ions and large molecules to flow through it.
research Mechanical Behaviour of Scalp Hair in Premature and Full-Term Neonates
Premature infants have less elastic hair than full-term infants.
research Targetoid Hair Regrowth Pattern in Alopecia Areata: A Case Series
A rare hair regrowth pattern can occur in some people with alopecia areata.
research Stiffness of Human Hair Correlates with the Fractions of Cortical Cell Types
Hair stiffness is higher when it has more para-like cortical cells.
research Unconventional haircare
Certain immune cells help hair growth by regulating iron in the skin.
research New insights into human hair: SAXS, SEM, TEM and EDX for Alopecia Areata investigations
Alopecia Areata causes significant structural and compositional changes in hair.
research Nanomechanical characterization of human hair using nanoindentation and SEM
Human hair's strength and flexibility vary by ethnicity, damage, and treatment.
research Case report: Exploring autosomal recessive woolly hair: genetic and scanning electron microscopic perspectives on a Japanese patient
A genetic mutation in the LIPH gene causes tightly curled hair that stops growing in some Japanese individuals.
research The mesenchymal component of hair follicle neogenesis: background, methods and molecular characterization
The document concludes that specific cells are essential for hair growth and more research is needed to understand how to maintain their hair-inducing properties.
research Hair density, hair diameter and the prevalence of female pattern hair loss
Hair loss caused by longer latent hair cycle and sudden miniaturization, not gradual follicle size reduction.
research A discrete transition zone between cuticle and cortex layers of a human hair fibre: changes observed in the presence of breast cancer
Breast cancer alters specific molecular structures in hair, which revert after cancer removal.
