In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.

This discussion explores advances in intravital imaging for visualizing stem cells, highlighting key discoveries and potential future developments; it reports no new experimental results.

This study found that finasteride maintained chemical and physical stability in various excipient mixtures, which may guide the development of stable topical delivery systems.

This review discusses treatment strategies for PCOS, focusing on using insulin-sensitizing medications alongside weight reduction and exercise to improve hyperinsulinemia and hyperandrogenism, and reports no new results.

This study suggests that adult hair follicle stem cells can survive and potentially differentiate into neuronal cells after being transplanted in a mouse model of traumatic brain injury, indicating promise for TBI therapy.

In this study, overexpression of the MtAnn3 gene in Medicago truncatula roots was associated with altered root hair growth polarity in a calcium-free environment.

This study examined hair mineral and free amino acid components in various diseases and found that when using effect size analysis, specific components related to diabetes and other conditions were identified, suggesting their potential as novel health indicators.

This review reports that while deep learning shows promise in diagnosing scalp disorders from images, challenges remain with data quality and model interpretability, suggesting that integrating explainable AI techniques is crucial for building trust and facilitating clinical adoption.

This study found that infrared thermography might be a useful non-invasive tool to help diagnose frontal fibrosing alopecia by identifying active phases of the disease.

This study presents a two-photon imaging method to visualize low-threshold mechanoreceptor axon terminals in live mouse forepaw skin, enabling repeated high-resolution imaging to study sensory circuits during development and adulthood.

This study used proteomics to identify various proteins in human hair, which may help develop novel biomarkers for hair health, disease, and aging.

People with X-linked hypohidrotic ectodermal dysplasia have no sweat ducts and less, thinner hair.

This study suggests that infrared thermography may be a useful noninvasive tool for diagnosing active phases of frontal fibrosing alopecia when combined with dermoscopy.

This study found that photoacoustic imaging can effectively measure follicle density and angles, even when follicles are not visible to the eye, providing a promising alternative to traditional photographic examination.

In this study, echocardiographic measures of cardiac function in women with polycystic ovary syndrome were found to be similar to those of healthy women.

This study reported that combined oral finasteride and topical 5% minoxidil treatment in men with male-pattern hair loss improved hair growth by initiating anagen in pre-existing but deficient follicles, yet the growth rates remained unchanged and did not normalize hair productivity.

This study found that scalp thickness and hair follicle depth were reduced in individuals with androgenetic alopecia, and MRI signal intensity was higher compared to those without the condition.

This study aimed to determine if MRI can assess anatomical changes in the scalp caused by androgenetic alopecia, but it reports no new clinical results.

This study found that among COVID-19 patients, a higher presence of the G allele in the IFITM3 rs12252 polymorphism correlates with increased inflammatory markers and disease severity, noting higher ESR, CRP, Fibrinogen, LDH, and D-dimer levels in severe cases compared to mild ones.
