research 1361 A novel cell surface marker for hair follicle dermal cells throughout hair morphogenesis and cycling
Researchers found that the Leptin receptor is a consistent marker for hair follicle dermal cells, which may help future hair research.
research Clinical Snippets
R-spondin2 may help treat hair loss, gene differences could explain baldness, a peptide's regulation is linked to psoriasis, B-defensin gene copies may affect a skin condition's risk and severity, and potential markers and targets for alopecia areata were identified.
research Contribution of hair density and hair diameter to the appearance and progression of androgenetic alopecia in Japanese men
Hair thickness matters more than density for baldness in Japanese men over 25.
research Faculty Opinions recommendation of De novo production of dermal papilla cells during the anagen phase of the hair cycle.
New cells join the hair's dermal papilla during the growth phase, possibly affecting hair thickness.
research AN OBSERVATIONAL STUDY TO STANDARDIZE THE DERMOSCOPIC FINDINGS OF NORMAL SCALP AND HAIRS IN MALE
Standardized data is essential for diagnosing scalp and hair conditions in males.
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 Regarding the Death of Density Debate
Achieving original hair density with transplants is unrealistic; skilled practitioners are essential for the best results.
research Examination of hair growth parameters in androgenetic alopecia in women using TrichoScan
TrichoScan is reliable for counting and measuring hair density but may not accurately assess hair types in women with hair loss.
research Assessment of hair density and caliber in white and Asian females with female pattern hair loss using folliscope
White females have higher hair density, while Asian females have thicker hair in hair loss cases.
research CD271 orchestrates skin structure, differentiation, and inflammation via PI3K/Akt and PKCα/ERK pathways
CD271 is crucial for maintaining healthy skin and preventing inflammation.
research Dendrobium officinale polysaccharide promotes angiogenesis as well as follicle regeneration and hair growth through activation of the WNT signaling pathway
Dendrobium officinale polysaccharide helps hair growth by activating the WNT signaling pathway.
research Comparative Analysis of Biological Properties of Large-Scale Expanded Adult Neural Crest-Derived Stem Cells Isolated from Human Hair Follicle and Skin Dermis
Skin-derived stem cells grow faster and are easier to obtain than hair follicle stem cells, but both can become various cell types.
research Hair diameter vs. hair density in male androgenetic alopecia
Hair loss is due to thinner hairs, not less hairs; hair diameter indicates balding progression and treatment effectiveness.
research Evaluation of Automated Measurement of Hair Density Using Deep Neural Networks
Deep learning can accurately automate hair density measurement, with YOLOv4 performing best.
research The relationship between psychological distress and neurotrophins in patients with alopecia areata: A crosssectional study
Alopecia areata patients experience more psychological distress, linked to certain neurotrophin levels.
research Study on Hair Distribution in Healthy Males for Hair Restoration Design
About 21.3% of young, healthy Chinese men experience hair loss. Hairlines are mostly linear or have a central protrusion. Hair is densest on the top and back of the head, and hair follicles usually have 1 or 2 hairs. This information can help in designing hair restoration procedures.
research Pinpoint white dots in the scalp: Dermoscopic and histopathologic correlation
Small white dots on the scalp seen with a dermoscope correspond to sweat ducts and vary with different hair disorders.
research Assessment of markers expressed in human hair follicles according to different skin regions
Different body parts have varying levels of certain hair follicle markers.
research Beyond the Epidermal-Melanin-Unit: The Human Scalp Anagen Hair Bulb Is Home to Multiple Melanocyte Subpopulations of Variable Melanogenic Capacity
The human scalp has different types of pigment cells in hair follicles with varying abilities to produce pigment.
research LB1671 Large-scale skin scRNA-seq profiling highlights distinct body site-specific ligand-receptor interactions and pathways in keratinocytes
Different body areas have unique skin cell communication patterns, explaining why certain skin diseases occur in specific regions.
research Regulation of itch-induced scratching by nucleus accumbens dopamine receptor-expressing neurons
Dopamine receptors in the brain influence itch-related scratching behavior.
research An oral French maritime pine bark extract improves hair density in menopausal women: A randomized, placebo‐controlled, double blind intervention study
French maritime pine bark extract significantly increased hair density in menopausal women.
research Peripheral patterns of calcitonin‐gene‐related peptide general somatic sensory innervation: Cutaneous and deep terminations
CGRP-IR axons may help maintain and renew tissues.
research Multipotent hair follicle stem cells promote repair of spinal cord injury and recovery of walking function

research Localization of mechanosensitive channel TRPV4 in mouse skin
TRPV4 helps sense pressure in mouse skin.
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 Trichothiodystrophy hair shafts display distinct ultrastructural features
Trichothiodystrophy hair is structurally abnormal with protein and organization issues.
research N1-methylspermidine, a stable spermidine analog, prolongs anagen and regulates epithelial stem cell functions in human hair follicles
N1-methylspermidine helps hair growth and reduces inflammation in hair follicles.
research 564 Subpopulations of dermal fibroblasts produce distinct extracellular matrices
Different types of skin cells create unique support structures that can affect skin cell growth and could help in skin repair.
