This study found that keratin-associated protein nanoparticles extracted from human hair significantly reduced clotting time, suggesting their potential as a hemostatic agent for bleeding control, though further research is needed to understand their precise role in coagulation processes.

Scientists made nanoparticles from human hair proteins to improve drug delivery.

This study found that PGA-4HGF nanoparticles enhanced hair growth in mice more effectively than 4HGF alone by increasing anagen phase duration and dermal papilla cell proliferation.

In this preclinical study, researchers found that combining equal ratios of high molecular weight keratin intermediate filaments and low molecular weight keratin-associated proteins from human hair led to the most extensive fibrinogen precipitation, suggesting potential for developing effective hair protein-based hemostatic materials.

This study found that hair with lower levels of keratin associated proteins reduced the foreign body response in mouse subcutaneous implant tests compared to hair with higher keratin levels.
