Clinical trials, also known as clinical studies or clinical research, are research investigations in which people volunteer to test new treatments, interventions, or tests to prevent, detect, treat, or manage various diseases and medical conditions. These trials are conducted in phases, each designed to answer specific research questions while ensuring the safety and efficacy of the intervention.

community Clinical Trial: N-Acetyl-Cysteine for Treatment of AGA in Men

5 upvotes 5 years ago

Verteporfin is being discussed for its potential to regrow hair and heal scars, possibly aiding hair transplants or replacing them. Some users are skeptical about its effectiveness, while others suggest combining it with microneedling for better results.

community I interviewed Kintor: GT20029 Clinical Trial Pictures. As well as KX826.

156 upvotes 1 year ago

GT20029 and KX826 are promising hair loss treatments, with GT20029 increasing hair count and KX826 showing significant results. KX826 may be a good alternative for those who can't use finasteride or dutasteride, though results vary.

community Pyrilutamide phase III clinical trial results released

in Research/Science 31 upvotes 2 years ago

Pyrilutamide did not show effectiveness in regrowing hair compared to a placebo, but it may still help maintain existing hair by preventing DHT from causing follicle miniaturization. Some users believe it could be beneficial when used with other treatments like minoxidil, finasteride, and dutasteride.

learn SCUBE3

What do clinical trials say about the safety and effectiveness of SCUBE3 for hair regrowth? No clinical trial of SCUBE3 for hair regrowth has been registered on ClinicalTrials.gov or published, so there is no human safety or effectiveness data. The evidence is limited to one 2022 laboratory and mouse study reporting that SCUBE3 activates hair follicle stem cells through TGF-beta signalling.

learn GT20029

research compound made to degrade androgen receptors in scalp

When will GT20029 be commercially available, and are there any clinical trials on its use? GT20029 is not approved or commercially available anywhere and remains investigational. A published 12-week Phase II study in 180 Chinese men reports hair-count gains over placebo, but no long-term or Phase III data exists, so any launch is years away at best.

learn Follistatin

Are there any clinical studies supporting follistatin as a hair loss treatment? There is no controlled human trial showing follistatin treats hair loss; the published work is mouse and laboratory biology on the activin/follistatin signalling system, plus one small 2011 phase 1 injection study of a combination product, so follistatin remains experimental and unapproved.

learn Centella

Ever wonder why your hair doesn’t grow back thick anymore? Maybe your scalp needs better blood flow: centella could help. There is no clinical trial of centella asiatica for hair loss and no study measuring scalp blood flow in people using it; the only hair-related evidence is a 2017 cell-culture study. Centella products are cosmetics that may soothe an irritated scalp, and the link between scalp circulation and pattern hair loss is itself unproven.

learn Clascoterone

Can I use clascoterone if I'm undergoing gender-affirming hormone therapy? No published clinical trial has tested clascoterone in people on gender-affirming hormone therapy, so its safety in that group is unknown. The FDA label reports low systemic exposure and no described effect on blood testosterone, but it also records HPA-axis suppression and raised potassium in a small minority of subjects.
