This study found that St. John's wort treatment for two weeks induced finasteride metabolism and reduced its plasma exposure in healthy men.

This article reviews the molecular interactions involved in hair follicle cycling and highlights the role of dermal papilla cells, but it presents no new research findings.

This study found that the human placenta extracellular matrix hydrogel restored the hair-inductive capacity of high-passaged dermal papilla cells, enabling them to regenerate new hair follicles when co-grafted with mouse epidermal cells.

This review discusses the critical parameters for MALDI IMS sample preparation in skin analysis and highlights its applications in wound healing, neoplasia, and infection research, but reports no new clinical results.

This study found that testosterone treatment in older hypogonadal men caused minor improvements in depressive symptoms and visuospatial memory, but overall, major cognitive benefits were not observed.

In this study, oral finasteride treatment for four weeks reduced the weight of the corpus cavernosum in rats but did not significantly affect erectile function.

This study found that polymeric nanoparticles retained more minoxidil and facilitated superior drug permeation compared to lipid nanoparticles, although premature drug release affected formulation performance.

This article reviews the proposed mechanism of minoxidil in treating androgenetic alopecia, suggesting it may prolong the anagen phase by modulating cell growth factors and vascular activity, but reports no new results.

This study found that ILK deficiency disrupts hair follicle development by impairing cell polarity and laminin-511 assembly, but these defects can be partially reversed with exogenous laminin-511.

In this study, different donor and recipient site preparation techniques for melanocyte-keratinocyte suspension were associated with similar repigmentation outcomes in stable vitiligo, but efficacy varied by body site.

This study found that polymorphisms in the KAP8.2 gene in Chinese Inner Mongolia cashmere goats are associated with variations in cashmere fibre diameter, suggesting its potential as a molecular marker for this trait.

This study found that maternal sub-maintenance nutrition reduced the density and branching ratio of secondary wool follicles in Merino sheep fetuses and identified genes potentially involved in these processes.

This study found that Sargassum muticum extract and apo-9′-fucoxanthinone promoted hair growth in rat and mouse models by increasing dermal papilla cell proliferation and activating certain signaling pathways.

This review discusses the effects of minoxidil on human skin fibroblasts, reporting its potential to inhibit lysyl hydroxylase activity and DNA synthesis, suggesting it may have antifibrotic applications for collagen-related skin conditions.

In this study, partially purified apple polyphenols were found to inhibit preadipocyte differentiation in mouse cells by reducing GPDH activity and triglyceride accumulation.

This review discusses the effectiveness of non-thermal, non-ablative devices like light-emitting diodes in treating various skin and hair conditions but reports no new clinical findings.

Acankoreoside J from Acanthopanax koreanum may help promote hair growth.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

This study indicates that targeting the PTH/PTHrP receptor may potentially stimulate hair growth, particularly for chemotherapy-induced alopecia, as observed in hairless and cyclophosphamide-treated mice.

This study found that autologous platelet-rich plasma injections showed no significant effect on hair regrowth in patients with alopecia areata totalis.

This study found that AHCC significantly reduced alopecia caused by Ara-C in neonatal rats and improved liver function affected by 6-MP and MTX in mice.

This study found that human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs) significantly prevented hair loss induced by dexamethasone in a mouse model and enhanced cell proliferation in human hair follicle cells, suggesting a protective effect against stress-related hair loss.

This study found that platelet-rich plasma may effectively increase hair follicle numbers in men with androgenetic alopecia, but changes in hair thickness plateaued after the second injection.

This study found that protein extracts from human hair demonstrated significant antioxidant abilities, protecting human dermal fibroblasts from oxidative stress, suggesting potential for biomedical applications.

This study suggests that the water fraction of Chrysanthemum zawadskii extract promotes hair growth by inducing telogen hair follicles in mice to enter the anagen phase and stimulating cell differentiation.

In this study, an ethanol extract of Crinum asiaticum was observed to significantly increase hair-fiber lengths and promote hair growth in rat vibrissa follicles and C57BL/6 mice.

This study observed that Cyp27b1−/− mice exhibited growth and skeletal abnormalities similar to those of Vdr−/− mice, despite differences like the development of alopecia in Vdr−/− mice, suggesting that 1α,25D3 may directly influence chondrocyte proliferation and differentiation.

In this study, oral collagen peptides increased certain gene expressions related to epidermis development and the hair cycle in hairless mice skin, suggesting potential links to hair health.

This study found that β-catenin is essential for hair follicle stem cell proliferation and may regulate this process through the PI3K/Akt pathway, suggesting its potential as a therapeutic target.

This study found that young C57BL/6 and BALB/c mice exhibit distinct regenerative patterns during ear wound healing, with greater wound closure but less regeneration in middle-aged C57BL/6 mice.
