Did you mean Androgen Signaling?

Glossary Androgen Signaling

process where male hormones bind to cell receptors

Androgen signaling refers to the process by which androgens, which are male hormones like testosterone, bind to specific receptors in cells to regulate various biological functions. This signaling pathway is crucial for the development and maintenance of male characteristics, but it also plays a role in conditions like androgenetic alopecia (pattern hair loss) by affecting hair follicle health and growth.

research Hair follicle stem cell differentiation is inhibited through cross‐talk between Wnt/β‐catenin and androgen signalling in dermal papilla cells from patients with androgenetic alopecia

95 citations , January 2012 in “British Journal of Dermatology”

This study found that androgens inhibit hair follicle stem cell differentiation by disrupting the Wnt signalling pathway in dermal papilla cells, but Wnt activation can restore differentiation.

research The Androgen Receptor Antagonizes Wnt/β-Catenin Signaling in Epidermal Stem Cells

46 citations , June 2015 in “Journal of Investigative Dermatology”

This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

research Regulation of masculinization: androgen signalling for external genitalia development

45 citations , April 2018 in “Nature Reviews Urology”

This review discusses the molecular mechanisms of masculinization involving androgen signaling and their roles in male embryonic development and conditions like hypospadias and prostate cancer, and reports no clinical results.

research Androgen modulation of Wnt/β-catenin signaling in androgenetic alopecia

39 citations , March 2018 in “Archives of Dermatological Research”

This review describes the molecular interactions between androgens and Wnt/ß-catenin signaling in androgenetic alopecia but reports no new experimental or clinical findings; the authors discuss potential Wnt/ß-catenin-targeted treatments for hair growth.

research Diet‐Induced Obesity Promotes Alopecia Through Oxidative Stress and Androgen Signalling in Female Mice

August 2026 in “Experimental Dermatology”

This study found that a high-fat diet exacerbates hair loss in female mice by increasing oxidative stress and androgen signaling in the skin, and that treatments with antioxidants or antiandrogens may help mitigate this effect.

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 New angles to attack beyond DHT

4 upvotes 2 years ago

Exploring hair loss treatments beyond DHT, including Minoxidil, pyruvate, Gt20029 targeting androgen receptors, and vasodilators. Other options like Kx826, adenosine signaling, growth factor topicals, and microneedling are also discussed.

community The Real Reason For Hair Loss?

9 months ago

Hair loss is linked to scalp fibrosis and tension, which result from chronic mechanical stress and androgenic signaling. Treatments include blocking androgens with finasteride, promoting hair growth with topical minoxidil, and improving scalp mobility through exercises.

community Minoxidil is NOT an Anti-androgen. No.

in Research/Science 43 upvotes 10 months ago

Minoxidil is not an anti-androgen; it is a growth stimulator and does not lower DHT like finasteride or dutasteride. Minoxidil can cause side effects like facial swelling and anxiety due to its vasodilator properties.

community Is there a topical androgen receptor blocker so we don't have to fuck with the enzyme and destroy our allopregnanolone, but go and hit the end target straight?

in Treatment 44 upvotes 2 years ago

The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.

learn GT20029

What is GT20029 and how does it work as a topical anti-androgen for hair loss? GT20029 is an investigational topical androgen-receptor degrader. One 12-week Phase II trial in 180 Chinese men found two of four regimens beat placebo on hair count; it is not approved or available.

learn Spironolactone

Who is spironolactone used for in androgen-related hair thinning, and who should avoid it? Studies of spironolactone for hair loss are mostly in adult women; its use is off-label, it is avoided in pregnancy and generally not used in men, and the US label advises potassium checks (DailyMed, Aldactone).
