research Stress-induced premature senescence of dermal papilla cells compromises hair follicle epithelial-mesenchymal interaction

35 citations , January 2017 in “Journal of Dermatological Science”

This study suggests that stress-induced premature senescence of dermal papilla cells may contribute to hair follicle aging by impairing critical epithelial-mesenchymal interactions and promoting inflammatory cytokine production.

research Androgenic Alopecia and Stress-Induced Premature Senescence by Cumulative Ultraviolet Light Exposure

27 citations , January 2002 in “Exogenous Dermatology”

In this study, researchers reported that chronic UV exposure may contribute to androgenic alopecia progression by influencing hair cycle changes and exacerbating solar elastosis in the scalp.

research 517 Regulation of the lipidome and lipid metabolism in prematurely senescent human dermal fibroblasts

November 2022 in “Journal of Investigative Dermatology”

This study found that different stressors causing premature senescence in fibroblasts resulted in distinct changes in lipid profiles, particularly sphingolipids, which may affect the behavior of senescent skin cells.

research Cellular senescence and polycystic ovary syndrome: mechanisms and therapeutic strategies from a new perspective

2 citations , December 2025 in “Annals of Medicine”

This review discusses the complex correlation between cellular senescence and PCOS, emphasizing senescence markers, mechanisms, and potential anti-senescence therapies, but reports no new clinical results.

research Immunohistochemical Patterns in the Interfollicular Caucasian Scalps: Influences of Age, Gender, and Alopecia

8 citations , January 2013 in “BioMed Research International”

This study observed that both Factor XIIIa+ dermal dendrocytes and microvasculature size decreased with scalp aging and that alopecia changes resembled stress-induced premature senescence.

community The Real Cause Of Androgenetic Alopecia

675 upvotes 1 year ago

Androgenetic alopecia is caused by DHT affecting hair growth. Finasteride and minoxidil are used to manage hair loss by blocking DHT and promoting hair growth.

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.

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 Balding without a family history

in Chat 6 upvotes 9 months ago

The user is experiencing hair loss without a family history and suspects stress or telogen effluvium (TE) as the cause, despite using finasteride without results. Others suggest stress, vitamin deficiencies, or other conditions could be factors, and some mention that balding can occur without a family history.

community Ray Peat: Testosterone Isn’t the Culprit, Prolactin and Cortisol Drive Hair Loss (2016)

in Research/Science 110 upvotes 10 months ago

Prolactin and cortisol are identified as key factors in hair loss, with stress hormones impacting hair shedding. Finasteride and minoxidil are effective treatments, while DHT's role and individual sensitivity are significant factors.

learn procapil

Could pairing Procapil with antioxidants be the power combo for stress-induced hair thinning? Procapil combined with antioxidants may effectively combat stress-induced hair thinning.
