A young boy's uncombable hair is due to a rare genetic condition that usually improves over time.
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 The biology of hair shape
Hair shape is determined by genetic, molecular, and cellular factors.
research Microscopic Study concerning Hair Form of One Family in the Mixed Blood between European and Ponapean
Hair form in mixed-blood families varies due to hereditary twist-knots and pigment formation.
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 New aspects of the structure of human hair on the basis of optical microscopic observations of disassembled hair parts.
Human hair's strength comes from a honeycomb-like structure and macrofibrils.
research A case of familial trichomegaly with synophrys in association with loose anagen syndrome
A 17-year-old girl and her brothers have a rare hair condition with long eyelashes, thick eyebrows, and easily pluckable hair.
research “Downy hair sign”—A clue to autoimmune disease in curly hair
Autoimmune diseases can change hair texture, but treatment can restore it.
research Modeling Dynamic Hair as a Continuum
The authors created a realistic and efficient method to simulate hair movement by combining fluid dynamics with individual hair strand behavior.
research An investigation of the association between structural proteins and lipids with scalp hair curvature
Lipids play a key role in determining hair curvature.
research Morphogenesis of the hair follicle during catagen
research Disulfide Cross-Linked Network Structure of Intermediate Filament and Matrix in Hair and Wool Cortices
Hair and wool strength is affected by the number and type of bonds in their protein structures, with hair having more protein aggregates than wool.
research Permanent Hair Waving
Permanent hair waving uses chemicals to create long-lasting curls.
research Low prevalence of twisted hair in anorexia nervosa
Twisted hair is rare in severe anorexia nervosa, found in only 2 out of 30 patients.
research Hair structure anatomy and comparative anatomy1 1Dedicated to the memory of the late Dr. R. E. Rivett whose untimely death prevented his role in co-authorship.
Human hair is complex and grows in cycles starting from embryonic life.
research Molecular modeling and structural characterization of a high glycine–tyrosine hair keratin associated protein
The 3D structure of a key hair protein was modeled, revealing specific helical structures and stabilization features.
research J. Cosmet. Sci., 59, 203-215 (May/June 2008) �Effects of permanent waving on changes of protein and physicomorphological properties in human head hair
Permanent waving damages hair protein and weakens hair, especially with repeated treatments using sodium thioglycolate.

research Mapping cell dynamics in human ex vivo hair follicles suggests pulling mechanism of hair growth
Hair growth may involve a pulling force from the outer root sheath.
research Microscopic Hair Changes Associated with Hair Coloring, Hair Waving and Hair Ironing in Iranian Women
Hair coloring, waving, and ironing cause more hair damage than not using these treatments.
research Improved two‐dimensional electrophoretic mapping of Japanese human hair proteins; application to curved and straight Japanese human hairs; and protein identification by MALDI MS and MS/MS quadrupole time‐of‐flight mass spectrometry
The study found that minor protein differences between curved and straight Japanese hair are unlikely to significantly affect hair structure.
research Single-Cell Transcriptomics Reveals the Molecular Anatomy of Sheep Hair Follicle Heterogeneity and Wool Curvature
The research identified genes that explain why some sheep have curly wool and others have straight wool.
research Understanding breakage in curly hair
Curly hair breaks due to mechanical damage and environmental factors, not chemical makeup, and needs ongoing care to prevent breakage.
