research Trichoscopy (hair and scalp videodermoscopy) in the healthy female. Method standardization and norms for measurable parameters
Researchers established normal hair and scalp characteristics for healthy women using trichoscopy.
research Differential Expression of Type I Hair Keratins
research Morphological and morphometric study of the androgenetic alopecic scalp using two- and three-dimensional analysis comparing regional differences
The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.
research The failure behavior of the anchorage of hairs during slow extraction
Growing hairs are easier to pull out than resting hairs due to different anchorage strengths.
research The changing patterns of hair density and thickness in South Korean women with hair loss: clinical office-based phototrichogram analysis
South Korean women with hair loss have lower hair density and thickness compared to healthy women.
research Histopathology of Hypotrichosis with Juvenile Macular Dystrophy
The research found that a specific gene mutation causes fewer hair follicles and disrupted hair growth cycles, leading to thin and short hair in people with Hypotrichosis with Juvenile Macular Dystrophy.
research Identification of factors contributing to phenotypic divergence via quantitative image analyses of autosomal recessive woolly hair/hypotrichosis with homozygous c.736T>ALIPH mutation
Different hair fiber development might explain why hair loss severity varies in patients with a specific genetic mutation, and treatments that thicken hair could help.
research Trichohyalin: A structural protein of hair, tongue, nail, and epidermis
research The Higher Number and Longer Duration of Kenogen Hairs Are the Main Cause of the Hair Rarefaction in Androgenetic Alopecia.
More kenogen hairs cause hair thinning in androgenetic alopecia, not hair miniaturization.
research Whn and mHa3 are components of the genetic hierarchy controlling hair follicle differentiation
Whn is crucial for hair growth in certain areas by controlling a specific gene.
research Preferential Crosstalk between Perifollicular Capillary Vessels and Dermal Papilla Cells during Hair Cycling Homeostasis
Enhancing blood vessel interactions with hair cells may help treat hair loss and skin aging.
research De novo filament formation by human hair keratins K85 and K35 follows a filament development pattern distinct from cytokeratin filament networks
Human hair keratins K85 and K35 create unique filament patterns important for early hair formation.
research Aging of hair follicle stem cells and their niches
Aging changes hair stem cells and their environment, leading to gray hair and hair thinning, but understanding these changes could help develop treatments for hair regeneration.
research Distribution of hairs in Chinese Han nationality
Chinese Han individuals have fewer hair follicles and hairs than Caucasians and Africans.
research Microanatomical Observations of Hair Characteristics of Red Fox (Vulpes vulpes), Golden Jackal (Canis aureus), and Gray Wolf (Canis lupus): A Comparative Study
Red fox, golden jackal, and gray wolf hairs have similar features but differ in length, thickness, and inner structure.
research Progressive Alopecia Reveals Decreasing Stem Cell Activation Probability during Aging of Mice with Epidermal Deletion of DNA Methyltransferase 1
Aging reduces stem cell activation, leading to hair loss in mice lacking a specific enzyme.
research Type II Epithelial Keratin 6hf (K6hf) Is Expressed in the Companion Layer, Matrix, and Medulla in Anagen-Stage Hair Follicles
K6hf is found in specific parts of hair follicles, nails, and tongue, and is linked to hair growth and structure.
research Trichoscopic findings of androgenetic alopecia and their association with disease severity
Hair thickness differences help diagnose hair loss severity.
research Single-cell transcriptomics reveals lineage trajectory of human scalp hair follicle and informs mechanisms of hair graying
The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.
research Special issue on epidermal and hair follicle differentiation, part 2
research 1390 Active hair growth is fuelled by conveyor-belt like differentiation of germinative layer cells
Hair growth is driven by cells that move and change like a conveyor belt.
research Monilethrix: an ultrastructural study
Monilethrix hair issues are due to problems in the hair's internodes.
research Human Hair Follicle and Epidermal Melanocytes Exhibit Striking Differences in Their Aging Profile which Involves Catalase
Hair follicle cells age faster and lose pigment due to less catalase, causing hair to turn gray.
research Decision letter: A multi-scale model for hair follicles reveals heterogeneous domains driving rapid spatiotemporal hair growth patterning
Understanding hair follicle communication can help treat hair loss.
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 TMT-based quantitative proteomics reveals the genetic mechanisms of secondary hair follicle development in fine-wool sheep
Key proteins influence wool quality by affecting hair follicle development in sheep.
research Quantification of hair follicle parameters using computer image analysis: A comparison of androgenetic alopecia with normal scalp biopsies
Hair follicles are smaller in people with androgenetic alopecia compared to those with normal scalps.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Local structure of human hair spatially resolved by sub-micron X-ray beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
