This study found that oregonin isolated from Alnus japonica exhibits strong antioxidant activity and may promote hair growth, suggesting its potential use in cosmetic products.

This study generated a transcriptomic map of human hair follicle compartments, providing a database for identifying compartment-specific gene expression which may aid in developing targeted treatments for hair follicle disorders.

This study identifies unique gene expression patterns in specialized fibroblasts within adult hair follicles, which advances understanding of their role in tissue regeneration.

This chapter discusses the composition, biocompatibility, and production methods of biomaterials like collagen, chitin, and silk for dermal substitutes, focusing on preclinical and clinical research, but reports no new clinical results.

This study observed that androgen treatment increased ROS production and TGF-β1 secretion in rat hair follicle dermal papilla cells, suggesting that the androgen-induced TGF-β1 is mediated by ROS.

This study found that human follicle dermal papilla cells promote survival, proliferation, and tubulogenesis of microvascular endothelial cells, highlighting their significant role in hair follicle vascular remodeling.

This study found that 3-Deoxysappanchalcone may stimulate hair growth in mice by promoting proliferation of hair follicle dermal papilla cells through WNT/β-catenin and STAT signaling modulation.

This study demonstrated that β-catenin signaling in CD133+ dermal papilla cells enhances postnatal hair growth by accelerating the proliferation and differentiation of keratinocytes in the murine hair cycle.

This study suggests that sinapic acid may promote hair growth in human hair follicle dermal papilla cells by activating specific signaling pathways and inducing the expression of growth factors.

This study found that their system effectively supports the rapid formation of human hair follicle organoids, providing a platform for studying hair regeneration and drug screening.

This study found that dengue virus infection caused inflammation and cell death in human hair-follicle dermal papilla cells, which may contribute to increased hair shedding observed during the epidemic in Taiwan.

This study found that L-ascorbic acid 2-phosphate could reduce DHT-induced DKK-1 expression in balding scalp cells, suggesting potential for treating androgen-driven hair loss.

This study found that Bacillus/Trapa japonica fruit ferment filtrate extracts enhanced human hair follicle dermal papilla cell proliferation through the Akt/ERK/GSK-3β signaling pathway, suggesting potential benefits for alopecia treatment.

Ent-kaurane-type diterpenoids from Isodonis Herba may promote hair growth by boosting cell proliferation.

This study found that stress hormones, particularly CRF, can inhibit hair growth and induce hair loss by affecting human dermal papilla cells and hair follicles, suggesting a functional HPA axis in these cells.

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 report discusses two cases of porokeratotic eccrine ostial and dermal duct nevus and porokeratotic eccrine and hair follicle nevus, suggesting they may represent a single clinical entity, but reports no therapeutic outcomes.

In laboratory settings, this study suggests that Serenoa repens and N-acetyl glucosamine with milk proteins may promote hair follicle vascularization through specific cellular interactions and actions.
