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.

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 The Real Reason For Hair Loss?

8 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 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 My understanding of how androgenetic alopecia works (plus FIN and DUT)

18 upvotes 4 years ago

Androgenetic alopecia is affected by scalp DHT levels, not sensitivity, with treatments like finasteride and dutasteride aiming to optimize these levels. Personalized DHT management is crucial for effective hair growth.

community The mechanism of androgenic alopecia

36 upvotes 11 months ago

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.

learn Finasteride

Does hair strand thickness decrease in men with androgenic alopecia? Can finasteride help restore it? Androgenic alopecia thins hair strands by miniaturizing follicles. The pivotal finasteride trials (1,553 men, 1 mg/day, two years) report increased hair counts and improved assessed appearance, but they measured density, not the diameter of individual strands, so the effect on thickness itself is not established.

learn Spironolactone

Who can safely use spironolactone for hair thinning and androgen-related hair loss? Women with androgen-related hair loss can safely use spironolactone under medical supervision.

learn Argan oil

Argan oil: Is it useful for androgenic alopecia, or just for making hair look nice? Argan oil primarily improves hair appearance but lacks proven effectiveness for androgenic alopecia.

learn Metformin

Does metformin help control DHT levels that trigger androgenic alopecia? Metformin has been shown to lower circulating androgens in women with PCOS, but no published study has measured scalp DHT, 5-alpha reductase activity in the follicle, or hair density in anyone taking it — so its effect on pattern hair loss is untested, and it is not a DHT blocker.

learn Microneedling

Does microneedling help with all types of alopecia, or only androgenic alopecia? Microneedling is most effective for androgenic alopecia, with limited evidence for other types.
