research Imbalanced redox dynamics induce fibroblast senescence leading to impaired stem cell pools and skin aging

7 citations , March 2025 in “Free Radical Biology and Medicine”

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

research 487 Exploring ribosomal RNA modifications and corresponding snoRNAs in human skin cell senescence

November 2024 in “Journal of Investigative Dermatology”

In this study, researchers investigated changes in ribosomal RNA modifications associated with stress-induced cellular senescence in human skin cells, identifying potential biomarkers and targets for interventions to mitigate skin aging.

research Continuous MEK inhibition by AZD6244 (ARRY-142886) results in exhaustion of the cutaneous keratinocytic stem cell pool and resembles senescence driven skin aging

2 citations , May 2008 in “Journal of Clinical Oncology”

This study found that patients with unresectable melanoma treated with AZD6244 experienced skin reactions, including depigmentation and papulopustular rashes, in patterns similar to those caused by EGFR inhibitors.

research 138: Induction of cellular senescence and hair follicle stem cell dysfunction upon p14ARF and p16Ink4a expression in the skin

July 2014 in “European Journal of Cancer”

p14ARF and p16Ink4a cause hair follicle stem cell aging and dysfunction.

research Oleanolic acid alleviates stress-induced alopecia via modulating brain-skin axis: Neuroprotection and dermal papilla cell senescence

community Cell senescence-targeted treatment for hair loss, has anyone tried any products/enzymes etc. that use this theory

5 upvotes 1 year ago

DHT causes hair loss by driving cells into senescence, and a polyphenol in black chokeberry may reverse this. A product using this theory is being considered for use alongside finasteride, minoxidil, and microneedling.

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 Countering oral minoxidil side effects by taking collagen supplements?

18 upvotes 2 years ago

Oral minoxidil may deplete collagen, potentially causing skin aging. Users discuss whether taking collagen supplements can counteract this effect.

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 Eirion Therapeutics Announces Potential Breakthrough Treatment for Hair Loss Based on First-in-Man Clinical Trial Results

in Update 415 upvotes 1 year ago

ET-02, a new hair loss treatment, shows promising results with a 6-fold increase in hair count, potentially outperforming minoxidil by activating stem cells in hair follicles. Further trials are ongoing to confirm its efficacy and safety, with potential market release in the future.

learn GHK-Cu

What is GHK-Cu and why is it said to be a "miracle" for hair? GHK-Cu is a copper peptide studied mainly for wound healing and skin repair; for hair loss the evidence stops at cell-culture and animal work, and no published human trial has tested it for androgenetic alopecia.
