research All-trans-retinoic acid inhibits mink hair follicle growth via inhibiting proliferation and inducing apoptosis of dermal papilla cells through TGF-β2/Smad2/3 pathway

10 citations , August 2020 in “Acta histochemica”

This study found that all-trans-retinoic acid (ATRA) inhibits mink hair follicle growth by reducing dermal papilla cell proliferation and inducing apoptosis, likely through the TGF-β2/Smad2/3 pathway.

All-Trans Retinoic Acid Modulates Proliferation And Apoptosis Of Secondary Hair Follicle–Dermal Papilla Cells In Cashmere Goats Via The TGF-β2/Smad2/3 Pathway

research All-trans retinoic acid modulates proliferation and apoptosis of secondary hair follicle–dermal papilla cells in cashmere goats via the TGF-β2/Smad2/3 pathway

March 2026 in “Frontiers in Veterinary Science”

This study found that all-trans retinoic acid (ATRA) inhibits proliferation and promotes apoptosis in secondary hair follicle-derived dermal papilla cells from cashmere goats, likely via the TGF-β2/Smad2/3 signaling pathway.

Network Pharmacology and In Vivo Experimental Analysis for Validating the Antifibrotic Potential of Punica Granatum Leaves Against Skin Scleroderma: The Role of Oxidative Stress, Inflammation and TGF-β1/Snail 1/p-Smad 3 Signaling Pathway

research Network pharmacology and in vivo experimental analysis for validating the antifibrotic potential of Punica granatum leaves against skin scleroderma: the role of oxidative stress, inflammation and TGF-β1/Snail 1/p-Smad 3 signaling pathway

April 2026 in “Inflammopharmacology”

This study found that Punica granatum ethanolic leaf extract may alleviate skin fibrosis in rats by modulating inflammation-related pathways and reducing dermal alterations.

5-Bromo-3,4-Dihydroxybenzaldehyde Promotes Hair Growth Through Activation of Wnt/β-Catenin and Autophagy Pathways and Inhibition of TGF-β Pathways in Dermal Papilla Cells

research 5-Bromo-3,4-dihydroxybenzaldehyde Promotes Hair Growth through Activation of Wnt/β-Catenin and Autophagy Pathways and Inhibition of TGF-β Pathways in Dermal Papilla Cells

7 citations , March 2022 in “Molecules”

This study found that 5-bromo-3,4-dihydroxybenzaldehyde (BDB) promoted hair growth in rat vibrissa follicles by activating Wnt/β-catenin and autophagy pathways and inhibiting the TGF-β pathway in dermal papilla cells.

4-O-Methylhonokiol Protects HaCaT Cells from TGF-β1-Induced Cell Cycle Arrest by Regulating Canonical and Non-Canonical Pathways of TGF-β Signaling

research 4-O-Methylhonokiol Protects HaCaT Cells from TGF-β1-Induced Cell Cycle Arrest by Regulating Canonical and Non-Canonical Pathways of TGF-β Signaling

5 citations , February 2017 in “Biomolecules & Therapeutics”

The authors reported that 4-O-methylhonokiol decreased TGF-β1-induced cell cycle arrest and oxidative stress markers in human keratinocyte cells, suggesting a potential protective role in TGF-β1-mediated cell cycle regulation.

community Reducing Fibrosis in Hair Loss: Topical Pirfenidone

59 upvotes 5 months ago

Topical pirfenidone is highlighted as an effective anti-inflammatory and anti-fibrotic treatment for hair loss, particularly in addressing perifollicular fibrosis, which may enhance the effectiveness of standard treatments like finasteride and minoxidil. The user also uses calcipotriol, MCT oil, ciclopirox shampoo, and benzoyl peroxide shampoo as part of their regimen.

community Will dht levels increased by creatine cancel out with finasteride

8 upvotes 1 year ago

Creatine may increase DHT levels, but its impact on hair loss is unclear and not well-studied. Many users report no significant hair loss while using creatine alongside finasteride, though some experience increased shedding.

community Amplifica: Hope or Cope? A Review of Their Pipeline

9 upvotes 1 month ago

Amplifica's AMP-303 showed a modest increase in hair growth, but results were inconsistent and potentially misleading. Hyaluronic acid and osteopontin are being explored for hair growth, with varying effects on different hair types and conditions.

community Creatine Does Not Increase DHT And Does Not Cause Hair Loss - Randomized Controlled Trial

308 upvotes 1 year ago

Creatine does not increase DHT levels or cause hair loss. Personal experiences vary, but scientific evidence shows no link between creatine and hair loss.
