Dermal Wnt/β-catenin signaling is important for the proper size and development of hair follicles.
research Guides: Open Access: Learn More
Vitamin D receptor is essential for preventing hair loss by regulating hair cycle stages.
research Dermoscopy in hair disorders
Dermoscopy improves diagnosis of hair and scalp disorders and can help avoid unnecessary biopsies.
research Three‐dimensional imaging and analysis of the surface of hair fibres using scanning electron microscopy
The new 3D imaging method accurately measures hair surface details quickly.
research Developmental and environmental determinants of hair steroids in children from birth to two years postnatally: A comprehensive analysis
Hair analysis can effectively assess long-term hormone activity in young children.
research Dexamethasone, a Synthetic Glucocorticoid, Induces the Activity of Androgen Receptor in Human Dermal Papilla Cells
Dexamethasone increases the activity of androgen receptors in human skin cells, which may link it to certain types of hair loss.
research 8 Hair follicles and associated glands as androgen targets
Androgens like testosterone affect hair growth and oil production differently across body parts and individuals.
research Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
research Exhaustive analysis of scalp hair regression: subjective and objective perception from initial hair loss to severe miniaturisation and drug-induced regrowth
Hair loss reduces hair thickness and coverage, but drug treatments mainly revive dormant hairs rather than reverse thinning; patients often undervalue their hair loss severity.
research Spectral histology of hair and hair follicle using infrared microspectroscopy
Infrared techniques reveal glycogen, unsaturated lipids, and calcium compounds in hair.
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 Interaction between dermal papilla cells and follicular epithelial cells in vitro: effect of androgen
Testosterone increases hair follicle cell growth when beard or axillary skin cells are present together.
research Simultaneous Quantification of Dexpanthenol and Resorcinol from Hair Care Formulation Using Liquid Chromatography: Method Development and Validation
Researchers created a reliable method to measure dexpanthenol and resorcinol in hair products.
research Thyroid hormone receptor β1 is expressed in the human hair follicle
Thyroid hormone receptor β1 is found in human hair follicles and helps them survive.
research Perspectives and Challenges of Hair Analysis
Hair is a complex organ, and understanding its detailed structure and growth phases is crucial for analyzing substances within it.
research Interaction between dermal papilla cells and follicular epithelial cells in vitro: effect of androgen.
Testosterone helps beard and axillary hair cells grow by releasing growth factors from dermal papilla cells.
research Analysis of hairless corepressor mutants to characterize molecular cooperation with the vitamin D receptor in promoting the mammalian hair cycle
Certain mutations in the hairless protein disrupt its ability to regulate the hair cycle.
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 LB821 Human hair follicle dermal papilla as an in vitro model to study stress-induced hair growth arrest
Stress causes hair loss by making the body produce cortisol, which stops hair cells from growing.
research 837 Characterization of cutaneous hormone production through analysis of skin secretions
Skin produces different hormones depending on body part and sex, and a new method can measure them.
research LB1609 The evolutionary trajectory of primate skin appendage traits
Humans evolved to have less hair and more sweat glands than chimpanzees and macaques.
research Water distribution in human hair microstructure elucidated by spin contrast variation small-angle neutron scattering
The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.
research Hair cortisol: What we know and what we don’t (yet)
research Cross‐sectional relation of long‐term glucocorticoids in hair with anthropometric measurements and their possible determinants: A systematic review and meta‐analysis
Higher glucocorticoids in hair are linked to increased obesity measures like waist size.
