30 / 1000+ results research Elucidating penetration pathways into the hair fiber using novel microscopic techniques.
The conclusion is that substances can penetrate hair fibers through multiple pathways, including both the cell membrane complex and the non-keratinous parts.
research Mapping penetration of cosmetic compounds into hair fibers using time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS)
Different oils penetrate hair differently; monounsaturated oils like olive oil penetrate better than polyunsaturated oils.
research Impact of Hair Damage on the Penetration Profile of Coconut, Avocado, and Argan Oils into Caucasian Hair Fibers
Different oils affect hair flexibility and strength, with their impact varying on whether hair is virgin or bleached.
research Raman spectroscopic analysis of L‐phenylalanine and hydrolyzed eggwhite protein penetration into keratin fibers
L-phenylalanine and hydrolyzed eggwhite protein deeply penetrate human hair.
research Hyaluronic acid: elucidating its penetration into, and effect on hair fibers using confocal Raman spectroscopy and biometric techniques
Hyaluronic acid in shampoo penetrated hair well, reduced frizz, and improved hair strength and moisture.
research Secondary ion mass spectrometric investigation of penetration of coconut and mineral oils into human hair fibers: relevance to hair damage.
Coconut oil can penetrate hair better than mineral oil, potentially protecting against damage.
research Diffusion behavior of poly(ethylene imine) into keratin fibers using microspectrophotometry
