This study found that mTOR signaling plays a crucial role in activating hair follicle stem cells by balancing BMP-mediated repression, essential for hair regeneration.

This study found that miR-148a plays a significant role in regulating skin homeostasis and hair follicle cycling, influencing stem cell activity and development in mice.

This study suggests that while PTH rP initially seemed to shorten the hair cycle by transitioning hair follicles from anagen to catagen, more relevant models indicate it ultimately accelerates and stimulates hair growth.

IL-6 contributes to hair loss by shortening the growth phase and causing hair follicles to regress.

In this study, researchers found that p75 neurotrophin receptor signaling affects apoptosis during hair follicle regression in mice, and altering its activity might help manage disorders involving early catagen entry.

This study found that continuous expression of epidermal growth factor in transgenic mice prevented hair follicles from entering the catagen phase, implicating EGF as a crucial regulator in hair cycle progression.

This study found that peripheral clock genes, particularly BMAL1 and Period1, modulate human hair follicle cycling, suggesting their potential as therapeutic targets for affecting hair growth.

This study found that Sophora flavescens extract may promote hair growth in mice by inducing earlier hair cycle changes and regulating growth factors in dermal papilla cells.

This study found that circadian clock genes are involved in regulating the hair growth cycle, suggesting a connection between daily rhythms and the longer hair follicle cycling process.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study found that epimorphin and a modified peptide, pep7, can stimulate hair follicles to shift from a resting phase to a growing phase in both an organ culture assay and in mice.

This study found that Erica multiflora extract promotes hair growth by enhancing dermal papilla cell activity and shifting hair follicles from the telogen to the anagen phase in both in vitro and in vivo models.

In this study, Nec-1s was found to promote hair growth and may target necroptosis and the Wnt/β-catenin pathway for potential treatment of hair loss.

In this study, topical application of α-methylspermidine during the telogen phase in mice induced hair growth by increasing the polyamine pool and mimicking the anagen phase's characteristics.

Isoquercitrin helps hair grow by activating certain cell processes.

This study found that the alcohol extract of Vernonia anthelmintica may counteract stress-induced hair follicle growth inhibition in mice, potentially offering a new approach for treating stress-related hair loss.

This study found that insect wax can significantly promote hair growth in mice in a way that is comparable to minoxidil, likely due to the upregulation of VEGF expression.

This study found that a mutant form of the FGF5s protein, FGF5sC93S, significantly increased hair count after 24 weeks of application on human scalps, suggesting its potential as a hair growth treatment.

This study reported that bioinks containing calcium molybdate nanoparticles and dermal papilla cells can promote hair regrowth in vivo by creating an anti-inflammatory environment and activating the mTOR signaling pathway in macrophages.

In their research, Yucel and colleagues found that CaV1.2 is expressed in hair follicle stem cells, facilitating anagen re-entry in a way not dependent on calcium flux.

This study found that Sanguisorba Officinalis Root Extract showed potential in reducing hair loss by inhibiting FGF-5 activity, extending hair growth phases in mice and reducing hair loss in human trials.

This study found that low-fluence intense pulsed light promoted hair growth in C57BL/6 mice by inducing an earlier and prolonged anagen phase and activating the WNT/β-catenin pathway.

This paper reviews several dermatological studies, including findings on hair growth, skin damage, bullous pemphigoid, and psoriasis treatments, and reports no new clinical results.

This research introduces the MHS Hair Restoration Protocol, which is a comprehensive approach aimed at restoring the hair follicle environment by modulating the gut-microbiome-endocannabinoidome axis and incorporating specific dietary and topical strategies, rather than focusing only on short-term hair count improvements.

This study identified a group of dermal fibroblasts near hair follicle stem cells in mice that facilitate hair regeneration by creating a biomechanically compliant extracellular matrix, enhancing stem cell activation and promoting a positive feedback loop for tissue regeneration.

This study found that orally administered hydrolyzed keratin peptide promoted hair growth and enhanced cellular proliferation and antioxidant capacity in mice and human cell models, suggesting its potential as a functional food ingredient for hair health.

In this animal study, Hirudo verbana leech extract significantly improved hair follicle regeneration and accelerated wound healing in rats, demonstrating potential as a safe and effective agent for skin repair due to its bioactive compounds with regenerative and anti-inflammatory properties.

This integrative review developed a Spiral Model to better represent human hair follicle dynamics and aging, which may assist in distinguishing natural aging from pathological changes and improving trichological interventions.

This review examines recent advancements in green and emerging microextraction techniques, such as SPME and DLLME, for more sustainable hormone detection in biological samples, emphasizing environmentally friendly solvents and bioanalytical applications.

This study demonstrated that a mouse model of telogen effluvium induced by lipopolysaccharide was effective for evaluating the therapeutic effects of topical minoxidil, which accelerated hair regrowth in treated mice.
