research Dihydrotestosterone-Inducible Dickkopf 1 from Balding Dermal Papilla Cells Causes Apoptosis in Follicular Keratinocytes
A substance called DKK-1 increases in balding areas and causes hair cells to die when exposed to DHT.
research Hairless Modulates Ligand-Dependent Activation of the Vitamin D Receptor-Retinoid X Receptor Heterodimer
Hairless protein can both repress and activate vitamin D receptor functions, affecting gene regulation.
research Functional mapping of the mouse hairless gene promoter region
Researchers found key regions in the mouse hairless gene that control its activity in skin and brain cells, affecting hair follicle function.
research EBF1 expressed in the dermal papilla regulates hair type and length
EBF1 controls hair type and length.
research Hair-Related Dysmorphophobia: A Mini-Review
Hair-related body dysmorphic disorder is common in hair loss patients and needs early recognition for proper treatment.
research Hair cycle and dermic follicular volume of the wild rodent, agouti (Dasyprocta prymnolopha), raised in captivity, in the northeast region of Brazil
Agoutis in captivity have more resting (telogen) hairs than growing (anagen) hairs, regardless of season or gender.
research Heterotypic cell contacts and basal lamina morphology during hair follicle development in the mouse: a light, scanning, and electron microscopic study at the site of tissue interaction
Heterotypic cell contacts likely help hair matrix cells differentiate during mouse hair follicle development.
research TrichoScan
TrichoScan accurately measures hair growth and loss, showing increased hair counts and thickness with treatment.
research Electron paramagnetic resonance (EPR) spectroscopy for investigating murine telogen skin after spontaneous or depilation-induced hair growth
EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.
research EEMCO Guidance for the Assessment of Hair Shedding and Alopecia
The document explains hair growth and shedding, factors affecting it, and methods to evaluate hair loss, emphasizing the importance of skin biopsy for diagnosis.
research Validating Hair Diameter Diversity in Androgenetic Alopecia via Hair Diameter Distribution Analysis
Hair diameter diversity helps assess hair loss, but its standard measure varies by individual and ethnicity.
research Hair Follicle Dermal Stem Cells Regenerate the Dermal Sheath, Repopulate the Dermal Papilla, and Modulate Hair Type
Hair follicle dermal stem cells are key for regenerating parts of the hair follicle and determining hair type.
research Mechanism of action of androgen in hair follicles
Testosterone affects hair follicles differently across body sites, with beard hair follicles showing more activity of a specific enzyme and presence of androgen receptors compared to scalp hair.
research Molecular elements of the regulatory control of keratin filament modulator AHF/trichohyalin in the hair follicle
The study concluded that a protein important for hair strength is regulated by certain molecular processes and is affected by growth phases.
research Trichohyalin: A structural protein of hair, tongue, nail, and epidermis
research Human hair shaft proteomic profiling: individual differences, site specificity and cuticle analysis
Human hair proteins vary by individual, body site, and ethnicity, useful for forensics.
research 252 Follicle dermal papilla cells undergo chromatin remodelling processes in vivo and in vitro
Hair follicle cells change their DNA packaging during growth cycles and when grown in the lab.
research Correlation between element concentrations and x‐ray diffraction patterns in hair
Elemental composition of hair affects its x-ray diffraction patterns.
research A highly resistant structure between the cuticle and the cortex of human hair. II . CARB , a penetration barrier
CARB is a strong barrier in human hair that prevents dye penetration.
research Hair stress hormones in individuals with a recent suicide attempt experiencing a depressive episode
People who recently attempted suicide during depression showed signs of adrenal fatigue, but had higher DHEA levels around the attempt time.
research 132 Genetics of Stress Hormone Concentrations in Hair of Healthy Nursery Pigs and Their Relationship with Back Test Responses
Pig hair cortisol levels are inheritable and linked to stress responses, which could help select for more resilient pigs.
research Applications of Hair as a Record of Systemic Exposure to Cortisol
Hair cortisol content can indicate cortisol exposure and varies with age, puberty, and BMI in youth.
research Balding hair follicle dermal papilla cells contain higher levels of androgen receptors than those from non-balding scalp
Cells from balding scalps have more androgen receptors than cells from non-balding scalps.
research Immunohistochemical analysis of tissue remodelling during the anagen—catagen transition of the human hair follicle
The inner root sheath is vital for hair follicle stability during growth changes.
research New frontiers in human hair follicle (neuro‐)endocrinology
Human scalp hair follicles can produce and respond to several hormones, affecting hair growth and pigmentation.
research Fine structure and immunocytochemistry of monotreme hairs, with emphasis on the inner root sheath and trichohyalin‐based cornification during hair evolution
Monotreme hair structure and protein distribution are similar to other mammals, but their inner root sheath cornifies differently, suggesting a unique evolution from reptile skin.
research The combination of hair follicle-specific marker LHX2 and co-expressed marker can distinguish between sweat gland placodes and hair placodes in rat
LHX2, with other markers, can identify hair placodes in rats.
research The ultrastructure of the interfollicular epidermis of the hairless (hr/hr) mouse
