research PAK4 signaling in health and disease: defining the PAK4–CREB axis

81 citations , February 2019 in “Experimental & Molecular Medicine”

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

research Quercitrin Stimulates Hair Growth with Enhanced Expression of Growth Factors via Activation of MAPK/CREB Signaling Pathway

25 citations , September 2020 in “Molecules”

In this study, quercitrin was reported to promote hair growth and cell viability in cultured human dermal papilla cells by enhancing cellular energy metabolism and growth factor production via MAPK/CREB signaling.

research Activation of cAMP Signaling in Response to α-Phellandrene Promotes Vascular Endothelial Growth Factor Levels and Proliferation in Human Dermal Papilla Cells

6 citations , August 2022 in “International journal of molecular sciences”

This study demonstrated that α-phellandrene promotes dermal papilla cell proliferation through a cAMP-mediated pathway and upregulates VEGF expression, suggesting its potential use in hair loss prevention.

research Dynamic interplay between IL-1 and WNT pathways in regulating dermal adipocyte lineage cells during skin development and wound regeneration

44 citations , June 2023 in “Cell Reports”

This study investigated dermal fibroblasts in mouse skin using single-cell RNA sequencing and identified signaling pathways that influence adipogenesis, finding that IL-1-NF-κB promotes, while WNT-β-catenin inhibits, the adipogenic potential of these cells, with implications for wound healing and scar formation.

research Melanogenesis‐promoting effect of Cirsium japonicum flower extract in vitro and ex vivo

4 citations , October 2021 in “International Journal of Cosmetic Science”

This study found that C. japonicum flower extract significantly increased melanin content and cellular activity in human melanocytes and may improve follicular depigmentation and vitiligo through cAMP signaling.

community Everything you ever wanted to know about Pelage Pharma's PP405: how it works and what to expect

126 upvotes 2 months ago

PP405 may encourage earlier hair growth and slightly increase visible hair count but does not reverse hair follicle miniaturization in male pattern baldness. It does not address damage to the dermal papilla or broken Wnt signaling.

community Polydopamine Synergizes with Quercetin Nanosystem to Reshape the Perifollicular Microenvironment for Accelerating Hair Regrowth in Androgenetic Alopecia.

11 upvotes 2 years ago

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.

community Is quercetin and houttunyia cordata extract actually effective for regrowth? Just heard of it for first time reading on Cleveland Clinic website

5 upvotes 2 years ago

Quercetin and houttuynia cordata extract may stimulate hair growth by enhancing cellular energy metabolism and increasing growth factor secretion. Quercetin has low oral bioavailability, and its natural tint might stain the scalp if used topically.

community New and Interesting HairLoss Studies/Papers/Reviews

44 upvotes 6 years ago

Hair loss treatments discussed include Dutasteride with Ketoconazole, tissue engineering strategies, and androgenetic alopecia therapies. Massage doubles follicular retention, improving treatment effectiveness.

community Creatine is the opposite of minoxidil !

324 upvotes 10 months ago

Creatine may counteract minoxidil's hair growth effects by closing potassium ATP channels, potentially leading to hair loss in predisposed individuals. Despite anecdotal reports, there is no conclusive evidence linking creatine to hair loss.
