This study reports that Plantago asiatica L. extract may promote hair growth by enhancing growth factor production and activating specific signaling pathways in hair follicle dermal papilla cells.

This study examined aging hair follicle stem cells in mice and found that inflammation reduction in dermal white adipose tissue can stimulate regenerative behavior, highlighting its role in hair follicle aging.

This study found that endothelin produced by hair follicle progenitors activates contractions in dermal sheath cells, facilitating hair follicle regression in the growth cycle.

This study found that scoparone increased the expression of certain pluripotency-related proteins in dermal papilla cells, suggesting a potential new mechanism for enhancing hair growth.

The hair follicle's connective tissue is a key source of a certain collagen in human scalp skin.

This study found that Clitocybin A from Clitocybe aurantiaca mushrooms may promote hair growth by enhancing cell-cycle progression and activating signaling pathways in dermal papilla cells.

This study found that red ginseng extract may stimulate hair growth in a mouse model by enhancing dermal papilla cell proliferation and activating skin antioxidant defenses.

This review discusses the various roles of skin-resident dermal white adipose tissue in hair growth inhibition, antibacterial responses, and wound healing, reporting no new empirical findings.

This study found that HIF-1α suppression in dermal papilla cells of androgenetic alopecia patients reduces the expression of trichogenic genes, suggesting it as a potential target for hair loss treatment.

This study suggests that exosomes from dermal papilla cells can regulate hair follicle stem cell proliferation via the Wnt3a/β-catenin signaling pathway, potentially informing treatment for human hair problems.

In this study, Oligonol® was shown to regulate gene expression related to cell proliferation and inflammation in human dermal papilla cells.

In this study, researchers discovered that HEY2+ dermal papilla cells exhibit stemness and contribute to dermal regeneration during wound healing, as shown by the expression of a reporter gene in regenerated dermal cells of tamoxifen-induced transgenic mice.

In this study, researchers found that androgen receptor activation in dermal papilla cells mainly affected the focal adhesion pathway and downregulated caveolin-1 gene expression, which could help identify new therapeutic targets for testosterone-related diseases.

Photobiomodulation helps protect hair follicle cells from damage caused by DHT.

This study found that Centipeda minima and brevilin A significantly reduced oxidative stress and inflammation in human dermal fibroblasts, suggesting their potential to protect against skin aging and inflammation.

This study presents a novel drug delivery system combining finasteride and cerium oxide nanoparticles, which successfully reversed cellular senescence and promoted hair regeneration in androgenetic alopecia mouse models, showing efficacy comparable to, and sometimes better than, minoxidil.

Androgens reduce THY1 in skin cells, leading to less fat, more fibrosis, and worse healing in males.

Wnt and SHH pathways help form hair follicles by coordinating cell processes.

This study observed that CXCL12 is highly co-expressed with androgen receptors in human hair follicle cells, and its inhibition via antibodies increased hair length, suggesting a potential treatment strategy for androgenic alopecia.

In this study, subthermal RF-CRET currents were found to alter key molecular mechanisms in dermal papilla cells, promoting proliferation and survival while enhancing markers associated with hair growth and maintenance, suggesting potential benefits for hair regeneration.

ATR04-484 ointment shows promise for treating skin issues from cancer therapies.

In this study, Betula platyphylla extract, particularly fraction H3-2, promoted human derma papilla cell proliferation and increased expression of certain growth factors, suggesting potential benefits for hair loss prevention.

This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.

This study found that the loss of papillary fibroblasts in the skin due to UV radiation is mainly caused by an uncontrolled inflammatory response, with T cells helping fibroblast survival.

This study found that chronic UVR exposure in mice and humans leads to a permanent loss of papillary fibroblasts in the upper dermis, which is associated with changes in the extracellular matrix.

This study found that treating human dermal fibroblast cells with ginsenoside Rd increased the expression of mRNA associated with the dermal-epidermal junction, suggesting potential as an anti-aging cosmetic ingredient.

This study found that dermal papilla cells exhibit stage-dependent variation in histone methylation during the hair follicle cycle and display distinct chromatin marker expression when transitioning to in vitro culture.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

The study reports that vitamin E improves hair-follicle growth and dermal papilla cell proliferation in vitro by modulating the lncRNA2919/STAT1/SHH axis in Angora rabbits, enhancing cellular antioxidant capacity.

Minoxidil helps hair growth by improving blood vessel function.
