research Influence of anionic surfactants on coacervation with cationic guar gum for hair care applications
A balanced mix of cationic guar gum and anionic surfactants improves hair conditioning and protection.
research The Study of Development of permanent wave for Additives of Collagen
Using 2% collagen in perms reduces hair damage while keeping curls.
research New aspects of the structure of human hair on the basis of optical microscopic observations of disassembled hair parts.
Human hair's strength comes from a honeycomb-like structure and macrofibrils.
research Protective effect of conditioning agents on Afro‐ethnic hair chemically treated with thioglycolate‐based straightening emulsion
Conditioning agents, especially jojoba oil and lauryl PEG/PPG-18/18 methicone, protect and strengthen chemically straightened Afro-ethnic hair.
research The adsorption behavior of cationic surfactant onto human hair fibers
A certain surfactant sticks to human hair, making it change from water-repelling to water-attracting, which could help in hair conditioning.
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.
