research Hair-Cycle-Dependent Expression of Parathyroid Hormone-Related Protein and its Type I Receptor: Evidence for Regulation at the Anagen to Catagen Transition

52 citations , May 2003 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

research Discovery of 7-Methoxy-6-[4-(4-methyl-1,3-thiazol-2-yl)-1H-imidazol-5-yl]-1,3-benzothiazole (TASP0382088): A Potent and Selective Transforming Growth Factor-β Type I Receptor Inhibitor as a Topical Drug for Alopecia

6 citations , January 2013 in “Chemical & pharmaceutical bulletin/Chemical and pharmaceutical bulletin”

In this study, TASP0382088 showed potent selective inhibition of the ALK5 receptor, significantly reducing Smad2 phosphorylation in mouse skin following topical application.

research Gene therapy for alopecia in type II rickets model rats using vitamin D receptor-expressing adenovirus vector

April 2023 in “Research Square (Research Square)”

In this study, gene therapy using a VDR-expressing adenoviral vector significantly improved hair growth and reduced cyst formation in Vdr -KO rats with alopecia linked to type II rickets, whereas control treatments did not show these effects.

research Regulation of Hair Shedding by the Type 3 IP3 Receptor

19 citations , May 2012 in “The journal of investigative dermatology/Journal of investigative dermatology”

This study found that mice lacking the type 3 IP(3) receptor in their hair follicles experienced repetitive hair loss and regrowth, indicating disrupted hair-cycle regulation potentially linked to specific signaling pathways.

research Luteinizing Hormone and Human Chorionic Gonadotropin Decrease Type 2 5α-Reductase and Androgen Receptor Protein Levels in Women’s Skin

13 citations , May 1998 in “The Journal of Clinical Endocrinology & Metabolism”

This study found that hCG decreased 5α-reductase and androgen receptor levels in skin samples from women in vitro, suggesting that human skin responds to LH/hCG treatment.

community Having androgen receptor density and sensitivity at wrong f*ing place

in Satire 7 upvotes 1 year ago

The conversation discusses hair loss treatments, focusing on the use of topical minoxidil, microneedling, finasteride, and dutasteride, while debating the role of testosterone and DHT in hair loss. It also touches on the potential liver health impacts of these treatments and the genetic sensitivity of hair follicles to androgens.

community 5 alpha reductase type 1 is in brain tissue producing the main endogenous gabaergic allopregnanolone, not 2. How can finasteride as a 5ar2 lower that?

27 upvotes 1 year ago

Finasteride and dutasteride are discussed for hair loss, with concerns about their effects on neurosteroids and potential side effects like depression. Alternatives like topical estrogen and lifestyle changes are considered, with varying opinions on mental health and hair regrowth.

community Dutasteride might be better for your hairline. Some people have more type 1 5AR activity in their scalp than others.

in Finasteride/Dutasteride 52 upvotes 3 years ago

Dutasteride might be better for hairline due to varying levels of 5AR activity in scalps. Genetic tests can determine if finasteride is enough or if dutasteride is needed.

community Theaflavin (Black Tea Extract) reduce DHT, androgen receptor activity and estrogen

6 upvotes 3 years ago

Theaflavin, a black tea extract, may inhibit DHT and androgen receptor activity, but its effectiveness for hair loss is debated. Users report no significant improvement with theaflavin, while some find beta sitosterol helpful.

community Physio-metabolic method of treating androgenic alopecia. Cold receptors. The relationship between DHT, cold receptors, minoxidil and antiandrogens.

2 upvotes 1 year ago

A method for treating androgenic alopecia using minoxidil, antiandrogens, exercise, and cold exposure to promote hair growth. Environmental factors and lifestyle changes, like diet and exercise, can improve treatment effectiveness.
