This study suggests that hair follicle dermal stem/progenitor cells play a key role in both hair regeneration and skin wound healing, with potential implications for preventing hair follicle miniaturization linked to aging or alopecia.

This review discusses the roles of DNA methylation in skin development and regeneration, highlighting its impact on embryonic skin lineage, homeostasis, and potential therapeutic targets, but reports no new clinical results.

This study found that low fluence photoepilation with intense pulsed light targets the pigmented area of hair follicles, causing temporary hair loss by inducing a catagen-like state without severe follicle damage.

This article explores the dynamic and energy-efficient nature of telogen hair follicles, challenging the notion of dormancy, and highlights their potential in advancing treatments for hair growth disorders.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

This review article summarizes the potential role of advanced medical therapies—using genes, cells, and/or tissue engineering—in treating various types of alopecia, by examining clinical research, basic studies, and ongoing trials.

This study found that topical administration of the TGFβ mimetic peptide DPS-1 stimulated hair growth in mice by promoting HDP cell proliferation and enhancing hair follicle morphology.

This study concluded that a liquid serum formulation delivered two fluorescent dyes to deeper follicular regions more effectively than nanoparticle systems.

This study found that transplanting trichogenous dermal cells significantly enhanced the restoration of in vivo-damaged hair follicles in a nude rat model, with a combination of dermal papilla and sheath cells proving more effective than either cell type alone.

Finasteride and minoxidil are effective, low-risk treatments for male hair loss, and patient education on these therapies is important.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

This study demonstrated that stress inhibited hair growth in mice, likely through substance P-dependent activation of immune cells, highlighting a brain-hair follicle connection.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This review discusses current knowledge on the biological mechanisms of different types of alopecia but reports no new clinical findings; the authors highlight future research directions, especially regarding epidermal stem cells and immune pathways.

This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study found that PBX1 enhances the proliferation and reprogramming of hair follicle mesenchymal stem cells by activating the AKT/GSK3β signaling pathway, promoting NANOG expression, and inhibiting apoptosis.

This article discusses strategies for changing hair color by regulating target genes in hair follicles using advanced delivery systems, but it reports no new experimental findings.

This study observed that primary hair follicles in Liaoning Cashmere goats had broader hair bulb widths compared to secondary follicles, with the difference diminishing during the anagen phase of hair follicle development.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

This study revealed key cellular dynamics and interactions during early embryonic mouse skin development, highlighting complex transitions from precursor states to diverse multilayered structures.

In this study, CD4+ non-haematopoietic, skin-resident stem cell-like populations were identified in both murine and human epidermis, suggesting they may serve as potential basal cell carcinoma precursors.

The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.

This study found that miR-23b and miR-133 significantly reduce mRNA and protein levels of specific target genes involved in Merino sheep hair follicle development, providing insight into molecular breeding for fine wool production.

This study reveals that hair follicles in mice and humans recruit epidermal Langerhans cells during skin inflammation via specific chemokine signaling pathways.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This review discusses the complexities of diagnosing and treating iron deficiency related to nutritional anemia and hair loss, concluding that routine screening and supplementation for hair loss are not yet supported by sufficient evidence.

This review argues that the immunocompetence hypothesis, linking masculine facial features to attractiveness through health benefits, lacks sufficient evidence and sidesteps alternative explanations.
