research Keratin formation in the hair follicle
Keratin fibrils in hair form and stop growing at specific points in the follicle.
research Cuticle damage and the tensile properties of human hair
Cuticle damage doesn't affect hair's tensile strength; the cortex is responsible for it.
research How different is human hair? A critical appraisal of the reported differences in global hair fibre characteristics and properties towards defining a more relevant framework for hair type classification
Human hair varies widely and should be classified by curl type rather than race.
research Studies of light scattering from ethnic hair fibers
Different hair types from various ethnic groups affect hair shine due to characteristics like thickness and shape.
research High-throughput phenotyping methods for quantifying hair fiber morphology
Hair fiber shape and curvature are not significantly linked when ancestry is considered.
research High-throughput phenotyping methods for quantifying hair fiber morphology
Quantifying hair shape is better than using racial categories for understanding hair characteristics.
research Evaluation method of the degree of hair damage. (I). Measurement of tensile strength of human hair by "the multi-point tension test method".
The method accurately measures hair damage and strength, revealing effects of cosmetics and metal correlations.
research Analysis of Morphological Changes on the Hair Surface by Heat Perm Treatment Method
Direct heat perms cause more damage to hair than softening heat perms.
research Clinical Signs of Hair Damage
Hair damage shows as fragility, dullness, and discoloration, varies by ethnicity, and is worsened by cosmetic procedures and diseases.
research Becker nevus of the face with asymmetrical growth of beard hair
Certain gene variations may increase the risk of alopecia, and platelet-rich plasma treatment can improve hair density in those with hair loss; a rare case of facial Becker's nevus was linked to uneven beard growth.
research Exploring the association between alcohol consumption and androgenic alopecia: a systematic review and meta-analysis
Alcohol may slightly increase the risk of hair loss, but the link is uncertain.
research MP45-12 CHRONIC ADMINISTRATION OF A LIMK2 INHIBITOR IMPROVES CAVERNOSAL VENO-OCCLUSIVE DYSFUNCTION THROUGH SUPPRESSION OF CAVERNOSAL FIBROSIS IN A RAT MODEL OF ERECTILE DYSFUNCTION AFTER CAVERNOSAL NERVE INJURY
Long-term use of certain prostate drugs can worsen erectile dysfunction by changing penile tissue, especially in rats with high blood pressure.
research Effects of Testosterone+Finasteride On Muscle After Spinal Cord Injury: A Randomized Double-Blind, Placebo-Controlled Pilot Study
Testosterone and finasteride improve muscle strength and size after spinal cord injury.
research Light scattering from human hair fibers
Researchers developed a new model for more realistic computer graphics rendering of hair by considering how light scatters on hair fibers.
research Light scattering from human hair fibers
Researchers developed a new model for more realistic computer graphics of hair by considering how light scatters on hair fibers.
research Variation in human hair ultrastructure among three biogeographic populations
Different populations have distinct hair structures related to their ancestry.
research Human hair form. Morphology revealed by light and scanning electron microscopy and computer aided three-dimensional reconstruction.
Hair follicle shape determines hair type: curly, straight, or in-between.
research Changes in structure and geometric properties of human hair by aging
Older people's hair becomes less shiny because it gets more uneven and curved.
research Platelet-Rich Plasma in Androgenic Alopecia: Indications, Technique, and Potential Benefits
Platelet-Rich Plasma (PRP) treatment can potentially increase hair density and quality in people with hair loss, but more research is needed to confirm its effectiveness.
research Acquired Uncombable Hair
A woman's hair changed to a dry, tangled texture that's hard to comb after treatment with spironolactone, suggesting the medication might cause such hair changes.
research Ethnic hair and skin: what is the state of the science?
Ethnic differences in hair and skin are significant and under-researched, requiring tailored dermatologic treatments and more study.
research Age, lifestyle and self‐perceptions of hair: Is there an association with hair diameter and tensile properties?
Older age and certain lifestyles are linked to thinner, weaker hair, while how you see your hair relates to its thickness.
research Platelet Rich Plasma Treatment of Androgenetic Alopecia in Men and Women
Platelet-Rich Plasma (PRP) treatment can significantly increase hair count and thickness in people with Androgenetic Alopecia (AGA) with minimal side effects.
research Hair Protection Effect of Wild Peach Leaf Extract Addition Treatment after Pigmentation Technique Hair Dyeing Procedure
Wild peach leaf extract improves hair strength, thickness, and shine after dyeing.
research A case of localized uncombable hair syndrome
A 4-year-old girl had a rare hair disorder affecting only part of her scalp.
research Cyberspace Chat: Platelet Rich Plasma (PRP): Pseudoscience or Fact
The article concludes that PRP might help with hair loss, but more detailed research is necessary.
research Optical coherence tomography examination of hair
OCT can effectively examine and reveal details about human hair and scalp conditions.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research Musculoskeletal and body composition response to high-dose testosterone with finasteride after chronic incomplete spinal cord injury—a randomized, double-blind, and placebo-controlled pilot study
Testosterone with finasteride improved muscle and bone health in men with spinal cord injury.
