This study found that intra-follicular Wnt signaling and dermal BMP signaling oscillate differently during hair cycling in mice, affecting hair wave propagation and phases of hair growth.

This article reviews the regulation of androgens in human skin and adrenals, highlighting their role in skin disorders, but reports no new research findings.

This review provides a framework for diagnosing acquired scalp alopecias and discusses both non-scarring and scarring types, but reports no new clinical results.

This study found that high levels of parathyroid hormone-related protein expression can result in the production of shorter hair shafts, likely through effects on angiogenesis.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

This review discusses major advances in understanding inherited hair diseases through genetic research and reports no new clinical results; the authors emphasize the potential for new preventive and therapeutic tools.

This study found that cutaneous pyridoxal 5'-phosphate hydrolase activity may be carried out by an enzyme different from the classical tissue-nonspecific alkaline phosphatase in human and mouse skin.

This literature review reported that fractional lasers, like the 1550-nm nonablative erbium-glass laser, may enhance hair regrowth by stimulating a wound healing process, but more randomized controlled trials are needed to confirm their effectiveness and optimize treatment parameters.

In this study, researchers found that coordinated intercellular Ca2+ signaling among basal stem cells in mice is crucial for cell cycle progression and tissue-wide communication during epidermal regeneration.

This study found significant differences in gene expression between newborn and adult skin, with infant skin notably increasing processes related to ECM organization, cell adhesion, and collagen fibril organization.

This study found that the retinol dehydrogenases SDR16C5 and SDR16C6 in mice play a crucial role in skin retinol dehydrogenase activity, affecting hair growth and gland functions without impacting survival.

This study found that chi-miR-30b-5p was more expressed in the telogen phase than in the anagen phase and inhibited dermal papilla cell proliferation by targeting CaMKIIδ.

This study suggests that PDCD4 regulates keratinocyte proliferation and contact inhibition, playing a role in epidermal homeostasis and wound healing.

In this study, cyclosporin was found to prolong the hair-existing phase in nude mice, while corticosteroids inhibited its effect and suppressed hair regrowth.

This study found that M30 may protect against cyclophosphamide-induced alopecia in mice by enhancing hair growth and preventing abnormal hair, suggesting its potential as a treatment.

This study found that a 5-mer peptide called P5 promotes hair growth by activating adiponectin receptor 1, suggesting its potential use as a topical treatment for alopecia.

This study suggests that porphyra-334 may have antiaging properties, promoting collagen synthesis, improving periorbital wrinkles, and supporting hair follicle growth through gene regulation.

This study found that Wnt5a expression may suppress cell differentiation and induce an inflammatory response in HaCaT keratinocytes, which could be relevant to psoriasis development.

This review discusses the complex role of Runx family genes in regulating stem cells in blood and skin tissues and reports no new experimental results.

This study found that vitamin C deficiency in SMP-30/GNL-KO mice affected gene expression related to hair growth and cell growth, resulting in delayed hair growth compared to those with adequate vitamin C.

This study suggests that thermal imaging may aid in diagnosing cellulitis, potentially improving patient care, although its applicability to certain cases requires further investigation.

This research detailed a single-cell atlas showing dynamic hair follicle stem cell states associated with the hair cycle during aging in mice, highlighting differences in chromatin landscape linked to stem cell differentiation and quiescence, and providing a foundation for future exploration of aging reversal.

This study found that applying a formulation derived from Bacopa procumbens significantly promoted hair growth, pigmentation, and follicular cycle acceleration in mice compared to minoxidil, potentially offering a new therapeutic approach for hair health.

This article explores the complexity and significance of the hair follicle, emphasizing new insights into its biological roles and the involvement of p53 in follicular regression.

In this study, clinicians are advised to perform trichography regularly on Pomeranians with HCA, as significant hair abnormalities, especially TN, may affect hair quality; further research is needed to understand the underlying mechanisms and treatment options.

This review highlights the importance of apoptosis in the hair cycle, particularly its role in hair follicle regression and loss, suggesting that understanding its mechanisms can aid in developing treatments to reduce hair loss and promote hair growth.

Topical caffeine improves hair loss intensity, speed, and shedding, and works better with minoxidil/azelaic acid.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

This review synthesizes recent research on how Wnt signaling regulates skin, hair follicle, and nail regeneration, highlighting its compartment-specific roles and discussing targeted strategies for treating conditions like alopecia, chronic wounds, and skin cancer.
