research Analysis of the Working Principle of Hair Dye
The document reviews the principles of hair dye, categorizing them into oxidative and non-oxidative dyes, with non-oxidative dyes further divided into temporary and semi-permanent types. By analyzing these principles, the study aims to improve the quality and safety of hair dyes, making the dyeing process safer and more convenient. The review highlights significant differences in the duration, application methods, and potential risks associated with each type of dye, suggesting that understanding these differences can lead to better and safer hair dye products.
research Percutaneous penetration of hair dyes
Hair dyes penetrate the scalp very minimally, less than 1%.
research Effect of antioxidants in protecting chemically damaged hair
This study investigated the protective effects of antioxidants, specifically ferulic acid and resveratrol, on chemically damaged hair. Using standardized bleached Caucasian hair strands, the research involved two stages: treatment with oxidative hair dye containing antioxidants and application of leave-in conditioners with antioxidants followed by simulated solar exposure. The results showed that both antioxidants effectively protected hair fibers, increasing denaturation energy by up to 35% and reducing protein loss compared to untreated hair. While they did not prevent cysteine oxidation during dyeing, they significantly reduced cysteine oxidation by about 50% during solar exposure. The study concludes that incorporating ferulic acid or resveratrol in cosmetic formulations effectively protects hair from oxidative damage caused by chemical processes and sun exposure.
