TLDR Treatments improved hair surface and scale structure but didn't increase certain bonds in the hair cortex.
The study investigated the structural changes in keratin from bleached hair treated with commercial reconstructive agents, shikimic acid, and dimethyl maleate using vibrational spectroscopy and scanning electron microscopy. Results showed that these agents interacted with both the cortex and cuticle regions of hair fibers, with more significant modifications observed in hair bleached three times compared to four times. Commercial agents were more effective than the model compounds in modifying hair fibers at the molecular level.
