This study found that among women with frontal fibrosing alopecia, 100% showed dermoscopic elements suggestive of the condition, with perifollicular erythema often indicating disease activity.

In this study, the bark of Spondias mombin showed potential anti-tumor effects in rats with induced cancer, reducing symptoms like hair loss and low food intake, but tachycardia was noted as a possible side effect.

This study found that water extracts of Spondias mombin bark led to significant recovery in rats with induced cancer, while alcohol extracts did not produce significant effects.

In this observational study of female undergraduate students, researchers found a significant correlation between the use of eyelash extensions and ocular side effects such as itching, lashes pulling out, and heavy eyelids, affecting 54% of participants during or after use.

This study suggests that the cell membrane complex in hair cuticles contains hydrophilic regions with disulfide bonds allowing polymer uptake and hydrophobic lamella-like lipid layers.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

This study found that novel RNA aptamers specifically inhibited FGF5-induced cell proliferation, suggesting their potential as candidates for treating FGF5-related diseases or hair disorders.

This review discusses the cutaneous manifestations associated with various substances of abuse, highlighting their importance for clinicians in recognizing and treating substance abuse disorders, and reports no new findings.

In this study, growing human hair follicles in a defined glycosaminoglycan hydrogel ex vivo promoted cell survival, proliferation, and activation of hair growth-related signaling pathways, suggesting GAG-based hydrogels could modulate the hair follicle growth cycle.

This review discusses the diverse clinical manifestations of mucopolysaccharidoses in children and emphasizes the importance of early diagnosis and treatment initiation, but it reports no new clinical findings.
