research Lipid loses and barrier function modifications of the brown‐to‐white hair transition
White hair has less lipid content and absorbs water differently than brown hair.
research The color of human hair
Hair color is determined by melanin types and gene activity.
research Dyeing behaviours of amino heterocyclic compounds as blue oxidative hair dye precursors applied to keratin fibres
1,2,3,4-tetrahydroquinoline compounds are great for stable, pure blue hair dye.
research Application of XANES profiles to X-ray spectromicroscopy for biomedical specimens: Part II. Mapping oxidation state of cysteine in human hair
Perming and bleaching damage hair differently, with bleached hair having more cysteic acid in the cuticle.
research Sunscreen remanence on the skin: a noninvasive real time in vivo spectral analysis assessing the quenching of specular ultraviolet A light reflectance
Sunscreens with UVA blockers effectively reduce skin fluorescence for several hours.
research Note on Isocholesterol, Coprosterol and the Classification of the Sterols
Isocholesterol is a confirmed and recognized sterol.
research Investigation of pH effect on cationic solute binding to keratin and partition to hair
Solute binding to hair keratin is mainly driven by hydrophobic interactions and changes with pH.
research The Region Coding for the Helix Termination Motif and the Adjacent Intron 6 of the Human Type I Hair Keratin Gene hHa2 Contains Three Natural, Closely Spaced Polymorphic Sites
research Element profiles of mouse hair: A concern for using hair as a timetable repository
Mouse hair element patterns vary, making it unreliable for tracking time.
research Correlation between element concentrations and x‐ray diffraction patterns in hair
Elemental composition of hair affects its x-ray diffraction patterns.
research Establishment of an evaluation method to detect drug distribution in hair follicles
Researchers developed a method to measure drugs in hair follicles and found that both water-loving and fat-loving drugs can be detected after being applied to the skin.
research Comparison of stratum corneum penetration and localization of a lipophilic model drug applied in an o/w microemulsion and an amphiphilic cream
The microemulsion delivered the dye deeper into the skin than the cream.
research Carbon quantum dots applied to the chemical sensing of cobalt ions and methylcobalamin
Carbon Quantum Dots can effectively detect cobalt ions and methylcobalamin in water.
research The Hair Pigmentation Unit and Hair Graying
Hair color is due to active pigment cells in hair during growth.
research Scattering from Elliptical Hair Fibers Based on Microfacet Theory
research Long-Term Intravital Imaging of the Cornea, Skin, and Hair Follicle by Multiphoton Microscope
Multiphoton microscopy can effectively image live cells in cornea, skin, and hair follicles over time.
research In-Situ Imaging Mass Spectrometry Analysis of Melanin Granules in the Human Hair Shaft
research 43687 Fitzpatrick Skin Phototypes: More than Just Skin Deep
Patients often overestimate their skin type, affecting sun protection and treatment plans.
research 1200 The biology of melanocytes
Melanocytes are cells that make skin and hair color and help protect skin from sun damage.
research Riboflavin-Sensitized Photo-Acceleration of Food-Grade Pigment Formation: Kinetic Insights, Mechanistic Analysis, and Application in Rapid Hair Coloration
Riboflavin with blue light speeds up hair dyeing, making it faster, safer, and long-lasting with less hair damage.
research Cosmetic assessment of the human hair by confocal microscopy
Confocal microscopy is better than scanning electron microscopy for studying hair in its natural state and understanding hair products' effects.
research 085 Coordinate expressions of cyclin-dependent kinase inhibitors and high sulfur protein in human hair follicles
research Grey hair: clinical investigation into changes in hair fibres with loss of pigmentation in a photoprotected population
Grey hair is wilder, drier, and less manageable than pigmented hair.
research Analyzing the laser-light reflection from human hair fibers. I. Light components underlying the goniophotometric curves and fiber cuticle angles.
The research found a way to measure hair surface changes by analyzing how light reflects off of it, and determined hair cuticle angles vary by hair length and color.
research Fluorescence Microscopy Study of the Sorption of Cationic Polymers on Hair
Polymer JR400 sticks to hair but washes off with detergent.
research Automated quantitative analysis of coat and skin coloration in laboratory animals
A new algorithm accurately analyzes animal coat and skin colors quickly and easily.

The new "differential stripping" method effectively measures how much substance gets into hair follicles.
research Study of the keratinization process in human hair follicle by X-ray microdiffraction.
Hair structure forms the same way inside and outside the body.
research Live imaging reveals chromatin compaction transitions and dynamic transcriptional bursting during stem cell differentiation in vivo
Stem cell differentiation involves gradual chromatin changes and dynamic gene activity.
