Female hair loss can be diagnosed using specific trichoscopy criteria.
research Mechanical stiffness across skin layers in human: a pilot study
The epidermis is the stiffest skin layer.
research Morphological Changes in Human Scalp Hair Roots during Deprivation of Protein
Not eating enough protein can cause hair roots to shrink and lose color, and hair to become thinner.
research Vertex Accentuation in Female Pattern Hair Loss in Asians
Asian women often experience distinct hair thinning at the top of the head.
research LB1081 Three-dimensional imaging of tight junction-network across multiple layers of human epidermis by array tomography using backscattered electron-mode scanning electron microscopy
The study found that tight junctions reach the top layer of the skin's stratum granulosum, not just the second top layer as previously thought.
research Scanning Electron Microscopic Study on Collagen Fibrils in the Mink Dermis during the Hair Cycle and Growth
Collagen fibrils in mink skin change structure during hair growth, becoming looser and thicker in the active phase.
research Therapeutic efficacy and safety of a 1927-nm fractionated thulium laser on pattern hair loss: an evaluator-blinded, split-scalp study
The 1927-nm fractionated thulium laser treatment significantly improves hair thickness and count in pattern hair loss patients.
research Variations in the optical scattering properties of skin in murine animal models
Male mice have thicker skin, causing more light scattering than females.
research Hair density, hair diameter and the prevalence of female pattern hair loss: reply from authors
Hair loss caused by longer latent hair cycle and sudden miniaturization, not gradual follicle size reduction.
research 성장기 모낭에서 큐티클층의 각질화 과정
The cuticle layer in hair follicles thickens during keratinization due to incomplete cytosol loss.
research Androgenetic Alopecia
The document concludes that signs of male and female pattern baldness include uneven hair thickness, yellow spots, skin discoloration around hair follicles, more thin and soft hairs, and many hair follicles with just one hair.
research Patient satisfaction following the use of a hair fiber filler product to temporarily increase the thickness and fullness of thinning hair.
The hair fiber filler product increased satisfaction and improved quality of life for people with thinning hair.
research Trichorrhexis Invaginata and Netherton’s Syndrome
Recognizing bamboo hair helps diagnose Netherton’s syndrome.
research The Microanatomy of Human Skin in Aging
Aging skin shows thinner layers, fewer hair follicles, and new biomarkers like increased space between cells and smaller sebaceous glands.
research Cryo-Electron Microscopy of Trichocyte (Hard α-Keratin) Intermediate Filaments Reveals a Low-Density Core
Trichocyte filaments have a low-density core and may include proteins for hair structure.
research Androgenic alopecia, premature graying, and hair thinning as independent predictors of coronary artery disease in young Asian males
Early balding, premature graying, and hair thinning can predict heart disease in young Asian males.
research Dermatologic applications of direct-to-consumer genomic analysis
Living near more dermatologists and using certain cancer screening tests lowers the chance of being diagnosed with advanced skin cancer.
research Pili annulati with fragility: Electron microscopic findings of a case
The study found that hair fragility in Pili annulati may be caused by cavities and damage within the hair shafts.
research Hair Follicle Miniaturization in a Woolly Hair Nevus
The boy with woolly hair nevus had thinner hair and abnormal hair follicles, which improved with treatment but worsened when treatment stopped.
research Three-dimensional ultrastructural analysis of human skin with the arrector pili muscle interacting with the hair follicle epithelium
The method effectively analyzes skin tissue changes, especially in the arrector pili muscle and nerve fibers with hair follicles.
research Self-assembled monolayer enhanced support-free two-photon polymerisation for microscale kinematic pairs
A new method creates precise, stable microscale structures with reduced friction and potential for complex designs.
research Features of skinfold thickness in Ukrainian men with alopecia areata
Men with alopecia areata have different body fat distribution compared to healthy men.
research The Cross-section Trichometer
The Cross-section Trichometer is a promising tool for measuring hair characteristics without cutting the hair and may have various clinical uses.
research A highly sensitive MEMS silicon‐hair device reproducing the function of hair follicle
The device mimics human hair follicles and detects tiny forces and moments with high sensitivity.
research Electron microscopic observation of skin and hair on a case of Netherton syndrome
Netherton syndrome causes specific skin and hair changes that help in early diagnosis.
research Trichoscopy I: Non-Cicatricial Alopecia
The document concludes that different patterns of hair thickness and scalp changes can help diagnose types of non-scarring hair loss.
research FEMALE CADAVER IN THE HAN TOMB NO. 1 X-RAY DIFFRACTION STUDIES ON TWO KINDS OF FIBROUS PROTEIN

research Mechanism research of yak hair stretching slenderization based on the changes of conformation and cell shape
Yak hair stretches mainly due to macromolecules slipping past each other.
research The structure of human trichohyalin : potential multiple roles as a functional ef-hand-like calcium-binding protein, a cornified cell envelope precursor, and an intermediate filament-associated (cross-linking) protein
Trichohyalin is a versatile protein involved in hair and skin structure.
