In this study, researchers found a significant decrease in the modulus of elasticity of hair shafts in premature neonates compared to full-term ones, potentially due to differences in disulphide bonds or microfibril arrangement.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This study explored a keratin, sodium alginate, and carboxymethyl chitosan hydrogel modified with tannic acid and found it to have promising wound-healing qualities, including similar elasticity to human skin, antimicrobial and antioxidant properties, and effective water retention. These attributes suggest potential applications in biomedical engineering.

Human hair's ability to get wet is complex and can change with treatments, damage, and environment.
