research OR2AT4, an Ectopic Olfactory Receptor, Suppresses Oxidative Stress-Induced Senescence in Human Keratinocytes

6 citations , November 2022 in “Antioxidants”

In this study, sandalore was found to activate OR2AT4, which inhibits senescent cell traits and restores proliferation in human keratinocytes, suggesting potential anti-aging applications.

research Protective Effect of Iris germanica L. Rhizome-Derived Exosome against Oxidative-Stress-Induced Cellular Senescence in Human Epidermal Keratinocytes

October 2023 in “Applied sciences”

In this study, Iris germanica L. rhizome-derived exosomes were found to reduce oxidative stress, enhance antioxidant enzyme transcription, and restore cellular function in human epidermal keratinocytes, suggesting potential protective effects against oxidative-stress-induced skin damage.

research Oxidative Stress and Hormone-regulated Dermal Papilla Cell-targeted Nanomodulators: Reverse Cellular Senescence for Androgenetic Alopecia Therapy

January 2026 in “Biomaterials Research”

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.

Irradiation-Induced Hair Graying in Mice: An Experimental Model to Evaluate the Effectiveness of Interventions Targeting Oxidative Stress, DNA Damage Prevention, and Cellular Senescence

research Irradiation-induced hair graying in mice: an experimental model to evaluate the effectiveness of interventions targeting oxidative stress, DNA damage prevention, and cellular senescence

January 2024 in “GeroScience”

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

research Oxidative Stress–Associated Senescence in Dermal Papilla Cells of Men with Androgenetic Alopecia

93 citations , February 2015 in “Journal of Investigative Dermatology”

This study suggests that oxidative stress may contribute to androgenetic alopecia by inducing premature senescence and secretion of hair growth inhibitors in dermal papilla cells from balding scalp.

community How ET-02 Works. Also no proof that it's better than Minoxidil. At least for now.

44 upvotes 1 year ago

ET-02, a PAI-1 inhibitor, is not proven to be more effective than Minoxidil for hair loss. Other treatments like finasteride, dutasteride, PP405, and AMP-303 are also discussed, focusing on cellular senescence and oxidative stress.

community Looks like a real cure to the root of baldness (DHT-induced senescence) was proven earlier this year

737 upvotes 3 years ago

A study that outlines the full model for androgenic alopecia (AGA) which links DHT to cellular senescence in dermal papilla cells, and suggests black chokeberry as a source of cyanidin 3-O-arabinoside polyphenol with potential anti-oxidant properties that could reverse this process. The post encourages reaching out to experts in anti-aging and longevity to research treatments involving the polyphenol.

community Pyrilutamide update: three months

33 upvotes 3 years ago

A user's 3-month experience with pyrilutamide to reduce hair shedding, and how it may not be strong enough to stop the thinning of their hairline. Other users mentioned the effectiveness of minoxidil and finasteride for treating hair loss.

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 PP405 Won't Work Long Term: Hair Follicle Damage Due to Abuse of the ISR System

67 upvotes 11 months ago

PP405 may damage hair follicles if used long-term, suggesting cycling might be necessary. Combining it with finasteride could help maintain hair growth.
