This study found that genetically variant peptides from human hair can reliably identify individuals despite differences in age and storage conditions, provided environmental and processing factors are controlled.

This research found that perming, combing, and stretching cause hair damage, leading to a significant reduction in keratin levels within a specific molecular weight range.

This study found that perming, combing, and stretching human hair lead to damage, as evidenced by a reduction in keratins with molecular weights between 67,000 to 43,000 daltons.

This study suggests that keratin peptide signatures in human hair shafts may potentially be used to distinguish gender and ethnicity, although further validation with larger samples is needed.

This study suggests that keratin peptide signatures from human hair shafts could potentially distinguish gender and ethnicity, though confirmation in larger studies is needed.

This study found that pepsin digestion was more effective than trypsin at identifying keratin-associated proteins in human hair shafts and confirmed that trypsin introduced a bias in the analysis of protein composition that pepsin can correct.

In this study, researchers developed a simplified and reliable method to prepare human hair shaft samples, achieving over 75% protein extraction efficiency and improved keratin sequence coverage, with the approach showing high reproducibility across different labs and operators.

This study suggests that keratin peptide signatures in human hair shafts could potentially be used to distinguish gender and ethnicity, though further research on a larger scale is needed.
