research Notch signaling is significantly suppressed in basal cell carcinomas and activation induces basal cell carcinoma cell apoptosis

18 citations , February 2017 in “Molecular Medicine Reports”

This study found that the Notch signaling pathway is suppressed in basal cell carcinomas and highly expressed in hair follicles, suggesting it might be a target for treatment strategies.

research The peptide AC 2 isolated from Bacillus-treated Trapa japonica fruit extract rescues DHT (dihydrotestosterone)-treated human dermal papilla cells and mediates mTORC1 signaling for autophagy and apoptosis suppression

9 citations , November 2019 in “Scientific reports”

This study isolated a bioactive peptide from Trapa japonica fruit and found that it may protect human dermal papilla cells from DHT-induced stress, suggesting potential for biomedical applications.

research Araliadiol Protects Human Keratinocytes From Oxidative Stress, DNA Damage, and Apoptosis via Activation of Antioxidant Signaling

January 2026 in “Frontiers in Bioscience-Landmark”

This study reported that, in a laboratory setting, araliadiol derived from Centella asiatica activated antioxidant pathways, mitigating urban particulate matter-induced oxidative stress and skin damage.

research VDAC2 Mediates the Apoptosis of Cashmere Goat Hair Follicle Stem Cells Through the P53 Signaling Pathway

June 2025 in “Animals”

This study found that VDAC2 promotes apoptosis in secondary hair follicle stem cells of Albas cashmere goats by activating the P53 signaling pathway, with knockdown of VDAC2 reducing apoptosis and a P53 inhibitor partially rescuing VDAC2-induced apoptosis.

research Angelica sinensis Induces Hair Regrowth via the Inhibition of Apoptosis Signaling

17 citations , January 2014 in “The American journal of Chinese medicine”

In this study, topical application of Angelica sinensis extract on mice promoted hair regrowth by influencing key hair cycle pathways and reducing keratinocyte apoptosis during the catagen phase.

community [Nov 2019] The peptide AC 2 isolated from Bacillus-treated Trapa japonica fruit extract rescues DHT (dihydrotestosterone)-treated human dermal papilla cells and mediates mTORC1 signaling for autophagy and apoptosis suppression

23 upvotes 6 years ago

A peptide from Japanese water chestnut fruit may help with hair loss by suppressing DHT's effect on hair follicle cell death, potentially serving as a finasteride alternative. The treatment's effectiveness and safety in humans remain uncertain.

community A new study by Deng and colleagues set out to explore differences between balding and non balding scalps...

39 upvotes 4 years ago

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

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

126 upvotes 3 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 Prevention of age-related beard graying in humans by the topical application of Eriodictyon angustifolium extract

5 upvotes 4 years ago

Topical application of Eriodictyon angustifolium extract can prevent and reverse age-related beard graying and darken gray hair by increasing melanin production. Sterubin, a component of the extract, also promotes hair pigmentation and protects cells from DNA damage.

community Short Peptides for Hair Loss: anyone tried any of these?

14 upvotes 5 months ago

Various peptides are discussed for treating male pattern baldness, with some available for topical use like GHK-Cu and Ac-KGHK, while others remain in research stages. Users are interested in experiences and sourcing these treatments.
