This study found that proteolytic activities in murine skin vary with hair cycle stages, with significant collagenase activity during the early anagen phase.

This study found that applying the right mechanical stretch to skin can activate hair stem cells and promote hair regeneration through a pathway involving WNT, BMP-2, and M2 macrophages.

In this study, Scalp Immersion Proxigraphy (SIP) was shown to produce more accurate measurements of linear hair growth rate than crude phototrichogram techniques, suggesting SIP's suitability for clinical trials monitoring hair growth.

This review discusses the use of helmet designs in integrative medicine and transcranial photobiomodulation, highlighting new developments and potential future advancements in sensor-controlled therapy helmets, but reports no new clinical results.

This study introduced a high-viscosity epoxy photoresist to enhance the fabrication of complex microstructures with monolithic integration and mechanical stability, enabling advancements in two-photon 3D printing for creating functional micro-mechanical devices.

This review discusses the evolution and development of smart and multifunctional microneedles, highlighting their potential future importance in medical applications, but it reports no new experimental results.

This commentary discusses the use of microscopes in hair restoration surgery but provides no specific results or new insights.

This review examines the roles of macrophages and fibroblastic cells in organ injury and repair, discussing their impact on outcomes ranging from regeneration to fibrosis, without presenting new clinical results.

This description of dystrophy hypotrichosis associated with juvenile macular dystrophy provides an overview of this rare disorder characterized by short hair from birth and progressive loss of central vision but reports no new findings.

This study found that MEGA PROTAC improved the prediction of ternary structures with higher maximum DockQ scores compared to the BOTCP method in 16 out of 22 test cases.

In this study, the researchers found that trichoscopy can effectively visualize scalp micropigmentation, identified by homogenous, grey to black circular dots similar to closely cut hair, potentially reducing the need for invasive procedures.

In this study, researchers observed that in nude mice, exogenous stimulations lengthened the hair-existing phase and shortened the no-hair phase, with minoxidil influencing male and female mice differently.

This study found that hair follicle stem cells are stiff with high actomyosin contractility, while hair germ progenitors are soft and enlarge during quiescence, influencing hair regeneration; inducing miR-205 reduces contractility and activates regeneration in mice.

Hair movement can indicate hair quality and health.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

This study found that Oncostatin M, via JAK-STAT5 signaling, keeps hair follicle stem cells inactive, and its removal leads to hair growth initiation in mice.

This review discusses the expression of circadian genes in hair follicles and their potential for monitoring circadian-rhythm-related conditions, reporting no clinical results; the authors suggest combining hair sampling with other assessments for better insight.

This study found that mouse hair follicle stem cells in a quiescent state exhibit greater chromatin dynamics and de-differentiation potential, suggesting higher cell fate plasticity compared to their proliferative or differentiated counterparts.

This review discusses the use of cultured hair follicles for studying hair growth regulation and reports the challenge of modeling the entire hair cycle in vitro.

In this study, researchers found that knocking down the transcription factor Csdc2 inhibited the proliferation of dermal papilla cells in cashmere goats, and identified its regulatory relationship with the gene Robo2, providing insights into the genetic mechanisms influencing cashmere fiber growth.

This study developed a double-wavelength laser scanning microphotometer to measure hair shaft and follicle absorbance, improving spatial resolution and reducing light scattering effects in vitro.

This study established a rapid and accurate ultra-performance liquid chromatographic method for chemical fingerprinting and analyzing Platycladi cacumen, effectively distinguishing batches based on geographical and climatic conditions.

This study demonstrated that degradable core-shell cryomicroneedles loaded with hair follicle organoids supported natural-like hair regeneration in mice, offering a promising approach for controllable follicular unit regeneration in baldness.

This study introduces a new multiaxial bioreactor system that uniformly stretches tissue-engineered skin grafts and improves skin tissue maturation through enhanced cellular distribution and environmental monitoring.

Hair growth is influenced by factors like genetics and nutrition, and more research is needed to understand hair loss and growth mechanisms.

This study found that only eumenorrheic polycystic ovary syndrome patients showed a temporal coupling between kisspeptin and luteinizing hormone pulsatile secretions.

This study found that melatonin treatment in Cashmere goat kids enhances the density of secondary hair follicles and improves Cashmere quality by regulating the MAPK pathway and reducing cell apoptosis.
