This study analyzed how professional hairstyling practices cause thermal damage to human hair, focusing on heat exposure and product use, and proposed a protocol for minimizing damage with heat protection strategies and optimal temperature recommendations.

The study analyzed how professional hairstyling practices, such as excessive heat and product use, cause thermal damage to hair, and it proposed a protocol that includes heat protection strategies and optimal temperature ranges to minimize this damage for hairstylists.

This study quantified the effects of chemical treatments like oxidative bleaching and hair relaxing on the movement characteristics of hair strands using a novel high-speed recording method.

This study found that stem cell factor combined with fibronectin and type IV collagen promotes migration of amelanotic melanocytes, which may help explain their movement during vitiligo repigmentation.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

This study found that disrupting the PRL gene in mice alters the timing of hair cycling events, causing earlier molts and changes in hair characteristics, particularly affecting female mice more significantly.

This study found that a 0.5% cationic guar gum and 0.5% anionic surfactant formulation formed stable coacervates with improved adhesion and coverage on damaged hair, suggesting it may enhance the effectiveness of hair conditioning products compared to other ratios.

This study identified 4,942 differentially expressed genes between Jiangnan cashmere goats and Changthangi pashmina goats, enriching pathways like PI3K-Akt and thermogenesis, which may influence cashmere fiber quality, offering insights for their genetic improvement.
