This study found that kukui nut oil (AMS oil) promotes hair growth in human hair follicle cultures by increasing PGF2α levels and activating Nrf2 signaling, and a human trial confirmed its efficacy in enhancing eyelash growth.

This research found that kaempferol, a flavonoid from hair growth-promoting plants, significantly enhanced human dermal papilla cell proliferation and inhibited specific signaling pathways, outperforming minoxidil, with topical application in mice promoting hair growth and thickness, indicating potential as a natural hair loss treatment.

This study investigated the effects of heat-treated Limosilactobacillus fermentum LM1020 on hair growth and reported increased hair density, improved cellular activity, and beneficial scalp microbiota changes in patients with androgenetic alopecia over 24 weeks.

This study found that an extract from Justicia procumbens may prevent hair loss in a mouse model of androgenic alopecia by enhancing hair follicle cell proliferation and improving hair characteristics.

In this study, repressing β-catenin/Lef1 signalling in mouse epidermis led to progressive hair loss, dermal cysts, and spontaneous skin tumors with sebaceous differentiation, indicating altered keratinocyte differentiation and potential tumourigenic processes.

In this study, researchers found that quiescent stem cells resist immune attack due to downregulated antigen presentation, which may help explain the immune evasion of early cancer-initiating cells.

This study found that transgenic mice overexpressing E2F1 in their epidermis developed skin tumors, confirming in vivo that deregulated E2F1 activity can contribute to tumor development.

This study found that deleting β-catenin in epidermis-specific VDR knockout mice did not prevent UVB-induced skin tumors, indicating β-catenin does not compensate for VDR's role in tumor suppression.

This study found that combining herbal extracts with PRP increased human dermal papilla cell proliferation via ERK and Akt protein regulation, suggesting its potential for developing hair growth therapies.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

This study reported that tryptanthrin, a compound found in indigo naturalis, effectively suppresses non-melanoma skin cancer in mice by reducing inflammation, inhibiting cell proliferation, and blocking specific signaling pathways associated with tumor growth.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

In this study, exosome-mimetic nanovesicles derived from neural progenitor cells promoted hair follicle regeneration in mice by activating the Wnt/β-catenin signaling pathway.

This study found that dexamethasone treatment reduced cell viability and growth factor expression in human dermal papilla cells, suggesting it inhibits hair growth.

This study found that the progesterone metabolite 3α-THP increased the proliferation and gene expression of human glioblastoma cells, suggesting a role in tumor progression.

In this study, herbal extracts commonly used in traditional medicine were observed to significantly increase the proliferation of human dermal papilla cells, suggesting potential as alternative therapies for enhancing hair growth.

This study found that Activin B at 10 ng/mL may promote vibrissae follicle growth in mice by enhancing hair matrix cell proliferation and cell cycle progression via ERK signaling pathways.

This study found that costunolide promotes hair growth in both lab-cultured human hair follicle cells and in live mice by modulating growth factor pathways.

This study found that Twist1 and Tcf4 synergistically regulate the hair follicle induction ability of dermal papilla cells by forming a complex with β-catenin, enhancing their biological properties.

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.

In this laboratory study, Camellia japonica fruit shell extract showed potential to mitigate hair loss by promoting hair cell growth and reducing harmful effects of DHT and oxidative stress.

This study found that LEF-1 expression influences dermal papilla cells' proliferation through Wnt signaling, impacting the potential for cashmere yield improvement.

This study developed a DPC cell line by introducing mutant CDK4, Cyclin D1, and TERT, making it a promising tool to study downstream signaling pathways activated by testosterone in androgenetic alopecia.

This study suggests that synthetic ceramides may promote hair growth by inducing proliferation of human dermal papilla cells through modulation of Wnt/β-catenin and BMP2/4 signaling pathways.

This study found that the Foxn1(-/-) nude phenotype significantly influences epithelial progeny in skin, with notable changes in stem cell niches not achievable in other models.

Wheat bran can boost hair growth by affecting cell cycle proteins and signaling pathways.

This study observed that piperonylic acid activated key signaling pathways in dermal papilla cells and increased hair growth markers, and a clinical trial showed users of a piperonylic acid formulation had more hair than those using a placebo, suggesting its potential for treating hair loss.

This study found that EGR1 promotes the proliferation of dermal papilla cells, suggesting its close association with hair follicle growth and development.

Using a combination of specific cell cycle regulators is better for safely keeping hair root cells alive indefinitely compared to cancer-related methods.

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.
