November 2023 in “ACS Applied Polymer Materials” In this study, the researchers developed a new method using H2O2/TiO2/UV for extracting human hair keratins rapidly, yielding higher protein and enabling the production of keratin films with better hemostatic performance and varied wound-healing properties compared to films from traditionally extracted keratin.

August 2014 in “PeerJ” This study found that proteomic analysis can distinguish hair samples across different ethnicities and body regions based on keratin protein levels, which may aid forensic hair identification.
This study found considerable variation in hair shaft proteomic profiles among Caucasian, African-American, Kenyan, and Korean subjects, with individual and site-specific differences observed.
This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.
January 2025 in “Scientific Reports” This study explored 25-hydroxyvitamin D3 levels in hair samples from participants in Aberdeen and suggested potential links between hair vitamin D levels, seasonal UVB exposure, and marine diet in both modern and archaeological contexts.
