570-600 / 1000+ results research [Contribution to hair medulla study (author's transl)].
Hair medullary cells in mammals vary in complexity, with humans having more structured cells similar to inner root sheath cells.
research [Nevoid bundle hairs].
Naevoid bundle hair is an unusual hair growth pattern where multiple hairs fuse together.
research The spectrum of hair loss in patients with mycosis fungoides and Sézary syndrome
Some patients with mycosis fungoides or Sézary syndrome experience hair loss, which may be similar to alopecia areata or linked to skin lesions, possibly due to abnormal T cells, and bexarotene can help treat it.
research Alopecia areata after HLA-identical BMT from an affected, sibling donor
Alopecia areata can be transferred through stem cell transplants from affected siblings.
research Signs of Potential Androgen Excess Across the Lifespan in a US-based Digital Cohort Study
Potential androgen excess signs vary by demographics and health, needing inclusive evaluation.
research Three-dimensional architecture of macrofibrils in the human scalp hair cortex
Human hair has a complex, variable structure with a consistent matrix and double-twist pattern.
research pH Dependence of the Coiled-Coil Structure of Keratin Intermediate Filament in Human Hair by 13C NMR Spectroscopy and the Mechanism of Its Disruption
Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.
research The cracking of human hair cuticles by cyclical thermal stresses
Frequent blow-drying causes cracks and breakage in hair cuticles.
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 “Castor Oil” – The culprit of acute hair felting
Castor oil can cause severe hair matting.
research Case report: Exploring autosomal recessive woolly hair: genetic and scanning electron microscopic perspectives on a Japanese patient
A genetic mutation in the LIPH gene causes tightly curled hair that stops growing in some Japanese individuals.
research Perspectives on Hair Evolution Based on Some Comparative Studies on Vertebrate Cornification
Hair in mammals likely evolved from glandular structures, not scales.
research Hair perms/straighteners and styling agents
Hair perms or treatments seem safe to use up to 3 to 4 times during pregnancy.
research Corkscrew Hair: A New Dermoscopic Sign for Diagnosis of Tinea Capitis in Black Children
Corkscrew hair may be a new sign for quickly diagnosing scalp fungus in black children.
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 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 New Aspects of the Structure of Human Scalp Hair-II: Tubular Structure and Material Flow Property of the Medulla.
The medulla in Asian scalp hair has a tubular structure that allows ions and large molecules to flow through it.
research Exploring a biological tissue from atomic to macroscopic scale using synchrotron radiation: example of hair.
Hair has unevenly distributed proteins and lipids, with lipids mainly in the cuticle and proteins in the cortex and medulla.
research Azimuthal Scattering from Elliptical Hair Fibers
Light scatters differently from elliptical hair fibers than from circular ones, and a new model better predicts this behavior, especially for shiny highlights.
