research In vitro evaluation of changes of hair fibers subjected to oxidation-reductive straighteners associated with dyeing
Straightening and dyeing damage hair structure.
research In-Situ Tensile Testing of Hair Fibers in An Environmental Scanning Electron Microscope (ESEM)
Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.
research The Catalog of Human Hair Keratins
Human hair keratins were cataloged, showing their roles in hair differentiation stages.
research Wetting behavior of human hair fibers
Human hair's ability to get wet is complex and can change with treatments, damage, and environment.
research Chronological ageing of human hair keratin fibres

Melanin in black hair protects it from sun damage better than light-brown hair.
research Perspectives on Hair Evolution Based on Some Comparative Studies on Vertebrate Cornification
Hair in mammals likely evolved from glandular structures, not scales.
research Ultrastructural localization of hair keratins, high sulfur keratin-associated proteins and sulfhydryl oxidase in the human hair
Hair proteins change location and structure as hair cells mature.
research Effects of silicone pretreatment on oxidative hair damage
Silicone pretreatment protects hair from damage and reduces color fading without interfering with bleaching or dyeing.
research Structural investigation on damaged hair keratin treated with α,β-unsaturated Michael acceptors used as repairing agents
Treatments improved hair surface and scale structure but didn't increase certain bonds in the hair cortex.
research Ultrastructural Characteristics of Neonate Scalp Hair
Neonate scalp hair is thinner, lacks a medulla, and has smaller follicles compared to adult hair.
