This study suggests that a candlenut oil nanoemulsion formulation could enhance hair growth activity in Sprague Dawley rats, with stability for up to 14 days at room temperature.

This study found that hair follicles in mouse skin use common activator/inhibitor signals to maintain cyclical hair growth across different regions, with varying dynamics influenced by distinct anatomical domains.

This study suggests that lithocholic acid may enhance hair regeneration in alopecia by activating vitamin D receptors in human dermal papilla cells.

This study suggests that Grateloupia elliptica extract may promote hair growth by activating wnt/β-catenin signaling and fostering dermal papilla cell proliferation.

This study found that Grateloupia elliptica extract may promote hair growth by activating wnt/b-catenin signaling and enhancing dermal papilla cell proliferation in rat and mouse models.

This study found that Clitocybin A from Clitocybe aurantiaca may promote hair growth in immortalized rat dermal papilla cells by enhancing cell proliferation and activating Wnt/β-catenin signaling and ERK pathways.

This study found that transcriptional regulation by Runx1 and cyclin-dependent kinase inhibitors plays a crucial role in maintaining quiescence and promoting fate decision flexibility in hair follicle stem cells.

In this study, the n-hexane fraction of wheat bran significantly promoted hair growth in rat vibrissa follicles and triggered the telogen-anagen transition in C57BL/6 mice, likely through cell cycle and Wnt/β-catenin signaling pathways.

In this study, Stat3 activation in transgenic mice led to a decrease in stem cells in the hair follicle bulge, suggesting its crucial role in epidermal growth and stem cell maintenance.

In this study, the Foxn1(-/-) nude phenotype was associated with an altered regulation of epithelial progeny in skin, offering a valuable model for investigating stem cell niche maintenance and regulation.

This paper reviews the diverse skin, nail, and hair changes caused by medications, highlighting hyperpigmentation, alopecia, and nail structural alterations, but reports no new data.

This study concluded that S. hexaphylla extract may improve androgenetic alopecia by reducing 5α-reductase and androgen receptor levels, inhibiting apoptosis, and promoting keratinocyte proliferation in experimental models.

This study found that Undariopsis peterseniana extract may promote hair growth by activating specific cellular pathways, suggesting potential for treating alopecia.

This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.

This study found that RXRα plays a critical role in hair cycling and keratinocyte functions in mice, likely through its interaction with VDR in epidermal cells.

This study identified new dietary ligands for the human vitamin D receptor, including curcumin and gamma-tocotrienol, which may influence its biological functions.

Ectodysplasin-A1 is crucial for developing hair, teeth, and glands.

This review discusses the histopathology of male-pattern baldness and highlights ongoing disputes over several aspects, including sebaceous gland size and follicle loss, reporting no new clinical findings.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

This study found that DGAT1 functions as a key enzyme in murine skin to regulate retinoic acid levels and prevent retinoid toxicity, impacting hair cycle and sensitivity to retinol.

This study found that coculturing human hair follicle keratinocyte stem cells with dermal papilla cells increased expression of the hair-specific keratin 6hf gene, which requires β-catenin/lef-1 signaling for hair differentiation.

Researchers created a fully functional, bioengineered skin system with hair from stem cells that successfully integrated when transplanted into mice.

This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.

This study demonstrated that bioengineered hair follicles reconstituted from embryonic skin cells and transplanted into hosts can restore physiological hair functions, suggesting potential applications for treating alopecia.

This study found that RANK-RANKL signaling regulates hair renewal and epidermal homeostasis in mice, revealing its role in initiating hair growth cycles and maintaining skin cell activity.

This research observed that dermal papilla cells have the potential to regenerate hair bulbs under preferred environmental conditions when associated with dermal sheath cells or exposed to specific growth factors.

This review discusses various techniques for evaluating hair shedding and alopecia but reports no new clinical results. The authors emphasize the value of specific clinical and instrumental methods in assessing hair growth.

This review discusses dermal white adipose tissue's roles in skin immunity, highlighting its antimicrobial function and interactions with other immune cells, but reports no new clinical results.

The document concludes that both internal stem cell factors and external influences like the environment and hormones affect hair loss and aging, with potential treatments focusing on these areas.

This study investigated the tensile response and morphological changes of different ethnic hair types using AFM, showing variations between virgin, chemically damaged, and conditioner-treated Caucasian hair under different conditions.
