This study concluded that Polyquaternium-10 conditioner softens the surface of the scale face on hair fibers.

This study found that while hair washed with hard water had higher magnesium deposits, it did not show significant structural surface changes compared to hair washed with soft water.

This study conducted a comprehensive analysis of methods for assessing surface roughness, highlighting that contact methods using profilometers provide accurate results for machine parts, while non-contact optical and laser methods offer high precision and efficiency without damaging surfaces.

This study found that adding hair fibers to friction materials increased their friction coefficient stability and impact strength while decreasing wear rates, with 1% hair fiber content notably improving performance.

This study showed that chemical and mechanical treatments significantly alter the nanoscale surface properties of hair, affecting its roughness, mechanical stiffness, adhesion, and surface potential.
