Research
360-390 / 1000+ resultsresearch Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
research Evaluation of hair humidity resistance/moisturization from hair elasticity.
Polyquaternium-70 shampoo is best for reducing frizz.
research Unveiling the link between surface physicochemistry and nanomechanical behavior in bleached and UV-irradiated human hair fibers
Bleaching and UV exposure significantly damage hair.
research A study of the photolightening mechanism of blond hair with visible and ultraviolet light
Blond hair lightens more with visible light directly, while ultraviolet light lightens it after washing by damaging other hair parts.
research Hypoxia improves hair inductivity of dermal papilla cells via nuclearNADPHoxidase 4‐mediated reactive oxygen species generation'
Low oxygen levels can make hair-growing cells better at growing hair through a process involving reactive oxygen species.
research Hair Preparations
Hair care products are regulated, with shampoos, conditioners, dyes, and styling products designed for cleaning, enhancing, and maintaining hair.
research Learning from hair moisture sorption and hysteresis
Hair moisture behavior helps tell apart different chemical treatments and reveals insights into hair structure.
research Exogenous and endogenous lipids of human hair
Removing external lipids from hair reduces moisture and increases strength, while removing internal lipids decreases water permeability.
research An ex vivo comparative study of the tensile strengthening efficacy of protein-derived actives on heavily bleached hair
Protein-derived ingredients can help strengthen bleached hair.
research Research on Hair Bleach that Causes Less Hair Damage and Smells Less Pungent than Ammonium Hydroxide
AMPD is a better and less damaging alternative to ammonium hydroxide for hair bleaching.
research Measurement of Hair Cortisol as a Retrospective Stress Marker: Effects of Prewashing, Pulverization, Temperature, and Sonication
Pulverization extracts more cortisol from hair, but any method works due to individual differences.
research A mechanical model of overnight hair curling
Longer time setting curls overnight leads to better curl retention.
research Cyclic combing of untreated and bleached human hair: Analysis of the time‐dependent breakage of hair through recording the formation of fibre fragments
Friction causes hair breakage during combing, and fragment count predicts hair strength.
research 3P343 Change of cell membrane complex of a hair fiber caused by hair damage
Chemical treatments damage hair more than UV exposure, making it thinner and less flexible.
research Hair Pores Caused by Surfactants via the Cell Membrane Complex and a Prevention Strategy through the Use of Cuticle Sealing
Surfactants damage hair, but sealing the cuticle can prevent this.
research Key locations of oxidative damage in human hair keratins after heat and ultraviolet light exposure
Heat and UV exposure damage hair structure by altering keratins.
research Chemical relaxers and curlers: Hidden danger
Continuous use of hair relaxers and curlers can cause hair loss, dryness, dandruff, thinning, greying, and split ends.
research Androgenetic Alopecia: A Revolutionary Thermal Stress Model - DHT is Not the Culpritأ
Male pattern baldness is mainly caused by brain heat stress, not DHT.
research Enzymatic Method for Assessing Hair Damage with Reduction and Subsequent Oxidation
Permed hair degrades faster and shows more damage after protease treatment compared to untreated hair.
research A reciprocal lattice approach to assessing the luster of hair fibers, based on scattering by periodically deformed cylinders
A new method helps understand hair shine and various products improve hair care.
research ENHANCED IN VITRO HAIR GROWTH AT THE AIR-LIQUID MINOXIDIL PRESERVES THE ROOT SHEATH IN CULTURED WHISKER FOLLICLES INTERFACE:
Culturing hair follicles at the air-liquid interface with minoxidil significantly boosts hair growth and preserves the root sheath.
research Natural ‘Green’ Sugar-Based Treatment for Hair Styling
Scientists created a non-toxic, sugar-based hair product that can style hair without damage.

research Formaldehyde replacement with glyoxylic acid in semipermanent hair straightening: a new and multidisciplinary investigation
Glyoxylic acid is a safer alternative to formaldehyde for hair straightening and effectively changes hair structure.
research A Raman spectroscopic investigation of the mechanism of the reduction in hair with thioglycerol and the accompanying disulphide conformational changes
Thioglycerol treatment at pH 9.0 with ammonia causes less hair damage and better waving than thioglycolic acid.
research Failure of intercellular adhesion in hair fibers with regard to hair condition and strain conditions
Hair breaks differently when wet or dry and is affected by its condition and treatments like perms and bleaching.
research Impact of acid (”progressive brush”) and alkaline straightening on the hair fiber: Differential effects on the cuticle and cortex properties
Glyoxylic acid straighteners cause more protein loss but have similar hair strength effects as traditional alkaline straighteners.
