research Sparse Hair on the Scalp
A 5-year-old girl has sparse, dry, and brittle hair but is otherwise healthy.
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 Functional analysis of keratin components in the mouse hair follicle inner root sheath
Keratin in mouse hair follicles is complex and plays specific roles.
research Genomic Characterization of the Human Type I Cuticular Hair Keratin hHa2 and Identification of an Adjacent Novel Type I Hair Keratin Gene hHa5
research Tight junctions form a barrier in porcine hair follicles
Tight junctions create a barrier in pig hair follicles that controls what can enter the skin.
research PATHOGENESIS OF GENETIC HUMAN HAIR DISORDERS
All major hair defects involve cuticle abnormalities.
research Towards Defining the Pathogenesis of the Hairless Phenotype
The hairless gene mutation causes baldness by disrupting hair follicle structure.

Hair follicles grow hair and release it through the skin.
research Monilethrix: an ultrastructural study
Monilethrix hair issues are due to problems in the hair's internodes.
research Hair follicles modulate skin barrier function
Hair follicles play a crucial role in regulating skin barrier function.
research Chapter 4 Cytomechanics of Hair
Hair's strength and flexibility come from its protein structure and molecular interactions.
research Isolation of intermediate filament assemblies from human hair follicles.
Researchers isolated and identified structural components of human hair follicles, providing a model for studying hair formation.
research Trichothiodystrophy hair shafts display distinct ultrastructural features
Trichothiodystrophy hair is structurally abnormal with protein and organization issues.
research Heterotypic cell contacts and basal lamina morphology during hair follicle development in the mouse: a light, scanning, and electron microscopic study at the site of tissue interaction
Heterotypic cell contacts likely help hair matrix cells differentiate during mouse hair follicle development.
research Isolating Hair Follicle Stem Cells and Epidermal Keratinocytes from Dorsal Mouse Skin
The method successfully isolates hair follicle stem cells and skin cells from mice for research.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Follicular dermal papilla structures by organization of epithelial and mesenchymal cells in interfacial polyelectrolyte complex fibers
Scientists created 3D hair-like structures that could help study hair growth and test treatments.
research KERATOSIS FOLLICULARIS WITH UNUSUAL INVOLVEMENT OF THE SCALP
A rare case of severe scalp hair loss and nail issues in keratosis follicularis was observed.

Hair casts can be treated with physical removal and special shampoos.
research Nanoindentation of Hair Cortex and Medulla Regions
research Hair dysplasias
Hair dysplasias involve various hair disorders causing fragility, breakage, and poor hair adhesion.
research Plica neuropathica: Bird's nest under dermatoscope
Plica neuropathica is a tangled hair condition that may be caused by hair damage or psychiatric issues and is treated by cutting the hair and addressing mental health.
research Preparing the hair follicle canal for hair shaft emergence
A specific type of skin cell creates an opening for hair to grow out, and problems with this process can lead to skin conditions.
research Quasi-Static Torsional Deformation of Single Hair Fibers: Application of a Modeling Approach and Results from Cosmetic Treatments.
The research found that twisting hair fibers can show changes in stiffness and damage, and help tell apart different hair treatments.
research Characterization of the Human Hair Shaft Cuticle–Specific Keratin-Associated Protein 10 Family
KRTAP10 proteins help form the hair shaft's tough outer layer by interacting with specific hair keratins.
