research Hemp Seed-Derived Exosomes Protect Against Dihydrotestosterone-Induced Chicken Feather Growth Inhibition

August 2025 in “Pharmaceuticals”

In this study, hemp seed-derived exosomes (E40) showed potential for counteracting DHT-induced inhibition of feather follicle development in chicken embryos by modulating critical signaling pathways, suggesting a therapeutic approach for alopecia.

research Module-based complexity formation: periodic patterning in feathers and hairs

47 citations , May 2012 in “Wiley Interdisciplinary Reviews-Developmental Biology”

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

research Deciphering principles of morphogenesis from temporal and spatial patterns on the integument

19 citations , April 2015 in “Developmental Dynamics”

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

research Hemp Seed-Derived Exosomes Protect Against Dihydrotestosterone-Induced Hair Growth Inhibition

April 2025 in “Research Square (Research Square)”

In this chicken embryo study, E40 hemp seed callus-derived exosomes counteracted DHT-induced inhibition of hair follicle development, suggesting potential for alopecia treatment and hair follicle regeneration.

research In Ovo Injection of CHIR-99021 Promotes Feather Follicle Development via Modulating the Wnt Signaling Pathway and Transcriptome in Goose Embryos (Anser cygnoides)

6 citations , May 2022 in “Frontiers in physiology”

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

community Does age play a role in how you respond to 5AR inhibitors? (finasteride/dutasteride)

in Research/Science 24 upvotes 2 years ago

The conversation discusses whether age affects the side effects and effectiveness of hair loss treatments like finasteride and dutasteride. Some believe early treatment yields better results, while others mention varied outcomes across ages and personal regrowth experiences without a clear consensus on age impact.

community Why is the general consensus that if you can’t tolerate 5AR Inhibitors you’re “cooked”?

in Research/Science 15 upvotes 11 months ago

Alternatives to finasteride for hair loss include minoxidil, alfatrodial, fluridil, pyrilutamide, and Nizoral. These treatments may not be as effective as finasteride but can help slow hair loss progression.

community What's "wrong" with oral minoxidil, exactly?

in Minoxidil 173 upvotes 1 year ago

Oral minoxidil can boost hair growth but may cause side effects like heart palpitations and increased body hair. Many prefer topical minoxidil due to fewer side effects.

community My dad 61y/o healed from full bald to full head of hair

178 upvotes 2 years ago

A user's 61-year-old father regained a full head of hair after four years on dutasteride for his prostate and five months of weight loss and exercise. The user decided to switch from finasteride to dutasteride and continue exercising, inspired by his father's results.

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.

learn Follistatin

glycoprotein that inhibits TGF-β and promotes hair growth by antagonizing activin

What is follistatin, and how does it influence hair follicle growth and regeneration? Follistatin blocks activin and related growth-inhibiting proteins, which in laboratory and animal work is described as keeping hair follicles in their growth phase; the only verifiable human evidence is a single small 2011 phase 1 injection trial, so follistatin remains experimental and is not an approved hair-loss treatment.
