research Do Hair Bulb Melanocytes Undergo Apoptosis During Hair Follicle Regression (Catagen)?
Hair follicle melanocytes die during hair regression.
research The Structure of the Amorphous Matrix of Keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Microscopical Characterization of Known Postmortem Root Bands Using Light and Scanning Electron Microscopy
The research found that postmortem root bands in hair are likely caused by the breakdown of a specific part of the hair's inner structure after death.
research Recent Advances in the Characterization of Hair of Mummies from the Chilean Andean Coast
The hair of two ancient Chilean mummies is well-preserved and contains high levels of heavy metals.
research Comparison of Quality Performance of Human Hair Types with Herbal Oils by Analysis Techniques
Grape seed oil improved hair quality the most, followed by rosehip and safflower seed oils, and reduced damage from shampoo.
research Kinetics and Equilibrium of Solute Diffusion into Human Hair
Hair absorbs molecules differently based on their size, charge, and love for water, and less at higher pH; this can help make better hair products.
research Formulation and Evaluation of Polyherbal Hair Dye
Polyherbal hair dyes are safer and more eco-friendly than chemical dyes.
research Naked Hair Shafts as a Marker of Cicatricial Alopecia
Naked hair shafts are significantly associated with scarring hair loss and may help diagnose it, especially when multiple are found.
research Investigation of Aging Effects in Human Hair Using Atomic Force Microscopy
Aging makes hair thinner and rougher, with less clear edges.
research The Nude Mutant Gene Foxn1 Is a HOXC13 Regulatory Target During Hair Follicle and Nail Differentiation
HOXC13 is essential for hair and nail development by regulating Foxn1.
research Reduction Mechanism of L-Cysteine on Keratin Fibers Using Microspectrophotometry and Raman Spectroscopy
L-cysteine slows down the breaking of bonds in hair due to electrostatic interactions.
research Independent DSG4 Frameshift Variants in Cats with Hair Shaft Dystrophy
Cats with abnormal hair had DSG4 gene changes causing hair problems.
research Curly Hair: Measured Differences and Contributions to Breakage
Curly hair breaks more easily, especially with chemical treatments, but simpler grooming reduces breakage.
research Hair Disorders
The document concludes that various hair disorders have different treatments, including medication, surgery, and addressing underlying causes.
