research SEM/SDD-EDS—An analytical tool to identify water borne micro minerals pick up in human scalp hair cuticle due to water quality
Water quality affects mineral content in hair, and coconut oil can protect against damage.
research Quantitative study of the human hair follicle in normal scalp and androgenetic alopecia
Alopecia causes smaller hair follicles and affects growth-related structures.
research Autophagy is essential for maintaining the growth of a human (mini-)organ: Evidence from scalp hair follicle organ culture
Autophagy is important for human hair growth and health.
research Dopamine is a novel, direct inducer of catagen in human scalp hair folliclesin vitro
Dopamine stops hair growth and pigment production in human scalp hair follicles.
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.
research Stress-sensing in the human greying hair follicle: Ataxia Telangiectasia Mutated (ATM) depletion in hair bulb melanocytes in canities-prone scalp
Hair greying is linked to reduced ATM protein in hair cells, which protects against stress and damage.
research Context-dependent effect of sPLA2-IIA induced proliferation on murine hair follicle stem cells and human epithelial cancer
sPLA2-IIA increases growth in hair follicle stem cells and cancer cells, suggesting it could be targeted for hair growth and cancer treatment.
research Identifying novel strategies for treating human hair loss disorders: Cyclosporine A suppresses the Wnt inhibitor, SFRP1, in the dermal papilla of human scalp hair follicles
Cyclosporine A may help treat hair loss by blocking a protein that inhibits hair growth.
research From in-vitro to in-vivo: Corporate development and efficacy of a topical hair growth agent derived from natural extracts
A natural extract-based hair growth product was developed and showed promise in preliminary tests.
research Analysis of the expression pattern of the carrier protein transthyretin and its receptor megalin in the human scalp skin and hair follicles: hair cycle-associated changes
The proteins transthyretin and megalin are more present in the growth phase of hair, suggesting they might affect hair health and growth.
research Characterization of the mechanical properties of the cortex region of human hair fibers by multiparametric Atomic Force Microscopy mapping
Atomic Force Microscopy is a more accurate way to assess hair damage and the effect of cosmetic treatments.
research Human scalp hair as a thermoregulatory adaptation
Tightly curled scalp hair helps reduce heat from the sun, protecting against overheating.
research Ultrastructural Characteristics of Neonate Scalp Hair
Neonate scalp hair is thinner, lacks a medulla, and has smaller follicles compared to adult hair.
research Investigation of aging effects in human hair using atomic force microscopy
Aging makes hair thinner and rougher, with less clear edges.
research A discourse on human hair fibers and reflections on the conservation of drug molecules
Hair analysis for drugs needs a better understanding of how drugs enter hair, considering factors like hair structure and pigmentation.
research A Guide to Studying Human Hair Follicle Cycling In Vivo
The document provides a method to classify human hair growth stages using a model with human scalp on mice, aiming to standardize hair research.
research Proteomic tools for the investigation of human hair structural proteins and evidence of weakness sites on hair keratin coil segments
Hair proteins have weak spots in their α-helical segments.
research The human hair: from anatomy to physiology
The document concludes that hair is complex, with a detailed growth cycle, structure, and clinical importance, affecting various scientific and medical fields.
research Quantifying whole human hair scalp fibres of varying curl: A micro‐computed tomographic study
Human hair varies in structure based on curl type, with high curl hair showing the most differences.
research Anti-Hair Loss Activity of Healthy Human Scalp-Derived Staphylococcus capitis KMH304 Ferment Filtrate in Human Hair-Follicle Dermal Papilla and Keratinocyte Cells
SCFF may help promote hair growth and scalp health.
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.
research Distribution of Glycolipid and Unsaturated Fatty Acids in Human Hair
Human hair has more unsaturated fats inside than on the surface, and certain lipids may help bind the outer and inner layers together.
research Determination of cortisone and cortisol in human scalp hair using an improved LC-MS/MS-based method
Cortisone in hair is a more reliable indicator of stress hormone exposure than cortisol.
research Evolution of long scalp hair in humans
Long scalp hair evolved for cooling and social signaling.
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 hair bulb contains different types of melanocytes with varying abilities to produce melanin.
