In this study, the researchers found that the absence of the NFI-C transcription factor delayed the hair growth cycle in mice by affecting key gene expressions and signaling pathways.

This study observed that treating human hair with NaOH led to partially removed cuticles, resulting in better fiber cohesion and mechanical properties similar to wool, unlike bleach or formic acid treatments, which weakened the fibers.

In this study, researchers developed an environmentally friendly hair coating from casein proteins and tannic acid, enhancing the tensile strength of virgin Asian hair by approximately 21% compared to untreated hair, while maintaining elasticity.

This study found that incorporating keratin extracted from hair into NBR modestly enhanced the mechanical properties and biodegradability of the rubber.

In this study, the relaxed overhand knot method demonstrated its effectiveness in measuring the self-friction coefficient of single hair fibers, revealing that sodium hydroxide treatment significantly increases friction and could aid microsurgical applications.
