480-510 / 1000+ results research Hair
Hair grows from living roots, is made of dead keratin, and goes through growth, rest, and shedding stages.
research Printable Hairline Designs and Hectographic Templates: Novel Tools for Hairline Creation and Graft Placement in Men
Printable templates improve hair transplant accuracy and efficiency.
research Investigation of optimum transplant and extraction density based on the data from the donor area of Chinese androgenetic alopecia patients: a multicenter, retrospective study
Optimal transplant density for Chinese male hair loss patients is 35-50 hair/cm², with minimum 106.88 hair/cm² left in donor area for esthetic satisfaction.
research ISHRS Best Practices Survey Project MODULE: Who Does What SUMMARY ANALYSIS
research The Viscoelastic Properties of Chemically Modified alpha-Keratins in Human Hair
Chemical modifications can alter hair's stability and flexibility, with hydrophobic interactions helping maintain structure in humid conditions.
research Effect of ethnicity and treatments on in situ tensile response and morphological changes of human hair characterized by atomic force microscopy
Different ethnicities and treatments affect human hair strength and structure.
research Studies of Developing Human Hair Shaft Cells In Vitro
research Electrophoretic analysis of human hair keratins
Family members have similar hair protein patterns, which could be useful for genetic studies.
research Methods in hair research: how to objectively distinguish between anagen and catagen in human hair follicle organ culture
A reliable system was developed to distinguish hair growth stages, aiding in identifying hair growth promoters or inhibitors.
research Human Hair as a Testing Substrate in the Era of Precision Medicine: Potential Role of ‘Omics-Based Approaches
Human hair shows promise for non-invasive medical testing, but more research is needed to standardize its use.
research 53013 A Literature Review and Guidance on Traction Alopecia in Hijab-Wearing Patients
Tight hairstyles under hijabs cause traction alopecia, worsened by prolonged wear.
research Histology of the Human Hair Follicle
Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.
research Age-related changes in the hair follicle and hair shaft in women in the parietal region
As women age, hair follicles decrease in number and hair width tends to reduce.
research Hair presentation test
The woman's hair loss pattern doesn't match typical conditions like alopecia areata or female pattern hair loss.
research Hear from the Assistants
research Scanning Electrochemical Microscopy of Iontophoretic Transport in Hairless Mouse Skin. Analysis of the Relative Contributions of Diffusion, Migration, and Electroosmosis to Transport in Hair Follicles
Hair follicles significantly enhance electroosmotic transport during iontophoresis.
research Lipid loses and barrier function modifications of the brown‐to‐white hair transition
White hair has less lipid content and absorbs water differently than brown hair.
research Analysis of Gene Expression in Isolated Single Hair Follicles: An Approach Using Semiquantitative Reverse-Transcriptase—Polymerase Chain Reaction
Researchers developed a new way to measure gene activity in single hair follicles and found that a specific gene's activity changes with different amounts and times of treatment.
research Exogen hair characterization in human scalp
The conclusion is that exogen is a unique hair cycle phase and the new sampling method specifically targets this stage, which may help in future hair loss research.
research Elastoinertial effects govern dynamic response of soft hair beds
Hair beds in fluid show nonlinear response due to viscosity, inertia, and elasticity.
research Hair Evaluation in Orthodontic Patients with Oligodontia
Most orthodontic patients with missing teeth also have hair disorders.
research Improving stable isotopic interpretations made from human hair through reduction of growth cycle error
The conclusion is that recognizing hair growth cycles can improve the precision of dietary and health assessments from hair analysis.
research Clinicopathological insights into the phenotypic variation of autosomal recessive hypotrichosis/wooly hair by c.736T>A LIPH mutation
The conclusion is that the variation in hair thinness in patients is mostly due to the amount of underdeveloped hairs, and treatments that thicken fine hairs might work for those with mild to severe conditions.
research Carbon-13 n.m.r. studies of keratin intermediate filament of human hair
Human hair keratin has a 40% α-helix structure that changes to a random coil in 8 M urea.
research Immunolocalization of junctional proteins in human hairs indicates that the membrane complex stabilizes the inner root sheath while desmosomes contact the companion layer through specific keratins
Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.
research Development of a New Grading Scale for Evaluating Overall Hair Density
A new reliable scale improves accuracy in measuring hair density and treatment response.
research 192 Three-dimensional ultra-high frequency ultrasound facilitates image processing to visualize microstructural changes of hair follicles and detects distinct disease phases of alopecia areata
3D ultrasound can detect hair follicle changes and disease phases in alopecia areata.
research The swelling behaviour of hair studied through the structural change of keratin protein during the permanent waving treatment
Hair structure changes immediately during perm treatment, with initial damage partially restored later.
research Quantifying variation in human scalp hair fiber shape and pigmentation
African hair is curled, Asian hair is thick, European hair is lighter, and chemical methods help identify hair color differences.
