research Reduction mechanism of L ‐cysteine on keratin fibers using microspectrophotometry and Raman spectroscopy
L-cysteine slows down the breaking of bonds in hair due to electrostatic interactions.
research Photoaggravation of hair aging
Sunlight exposure ages hair, making it brittle, stiff, and dry.
research Structural changes in trichocyte keratin intermediate filaments during keratinization
Keratin structure changes during keratinization, but the exact model remains uncertain.
research Analysis of heterogeneous reaction between reducing agents and keratin fibers using Raman spectroscopy and microspectrophotometry
The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.
