Users debate its potential effectiveness, with some hopeful due to Google's involvement, while others urge caution without more evidence.

Norwood 1-3 hair loss is considered normal in Russia and not balding. Using finasteride for Norwood 1-3 is seen as unnecessary and risky.

A user experienced increased pimples and cysts after two years on dutasteride, possibly due to hormonal changes. Suggestions included seeing an endocrinologist, using supplements like boron and DIM, adjusting diet, and reducing body fat to manage side effects.

A 21-year-old male with advanced hair loss (NW7) started using finasteride and minoxidil 10 months ago but hasn't seen much progress. He is pre-diabetic with stage 1 hypertension and is seeking insights on whether treating these conditions could improve hair regrowth.

The user is pausing finasteride for blood donation and is concerned about its effect on DHT levels. They plan to supplement with saw palmetto and pumpkin seed oil during the pause.

The conversation discusses whether finasteride's reduction of DHT and increase in scalp testosterone contribute to hair follicle miniaturization. Some participants argue testosterone does not cause miniaturization, while others suggest that even with reduced DHT, other androgens like testosterone may still contribute to hair loss.

Finasteride increased the user's estrogen levels by 51%, causing concerns about gynecomastia and sleep issues. Despite potential side effects, the user prefers continuing finasteride to prevent hair loss, considering it essential for self-esteem.

Switching from topical finasteride to oral Dutasteride and using Fluridil caused persistent testicular discomfort. The discomfort did not subside after stopping Fluridil, raising concerns about Dutasteride's role.

A 22-year-old male with hair loss is considering treatments like finasteride, minoxidil, and derma rolling after being diagnosed with MPB, vitamin D deficiency, and dandruff. He seeks advice on whether these treatments can realistically improve his hair density and achieve a healthier NW2.

The conversation is about whether the Ordinary's Multi-Peptide Serum for hair density can be mixed with finasteride. A video was mentioned that shows the serum being mixed with Stemoxydine.

A 54-year-old user shares progress after 3 years on dutasteride, following 15 years on finasteride, using 0.5 mg/day dutasteride, topical minoxidil every other day, and a peptide serum on alternate days. They experienced a significant shed during the transition but are now maintaining hair, noticing some new growth along the hairline.

The user has been using pyrilutamide 0.5% for over 7 weeks, alongside dutasteride, and noticed some hair improvement, particularly at the temples. They plan to continue and possibly try a 1% solution, with no shedding or side effects reported.

Finasteride improved the user's hair texture and growth, with some initial side effects like libido loss that eventually subsided. The user advises considering lifestyle factors alongside treatment and encourages others to start finasteride if hesitant.

The conversation discusses the comparison of Pyrilutamide Phase II US trial results with 1 mg finasteride for hair loss treatment. It mentions that the total hair count increase in the US trial was not as good as the China trial.

Dutasteride at 0.5 mg/day does not significantly alter allopregnanolone levels, but higher doses (2.5 mg/day) do. Dutasteride may also have anti-neuroinflammatory effects, but the impact on neurosteroids is still debated.

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.

A 31-year-old has been using finasteride, dutasteride, and oral minoxidil for hair loss. They noticed a sudden triangular thinning patch on their scalp and are seeking advice, questioning if it could be medication-related.

Pyrilutamide is a selective AR antagonist with a high binding affinity, making it effective in competing with DHT for androgen receptors. The 1% concentration is more effective than the 0.5%, but the latter may suffice for mild hair loss; the drug is considered a good option for those avoiding 5AR blockers due to side effects.

DLQ01, a prostaglandin F2α analog, shows promise for hair growth by directly stimulating PGE2/PGF receptors without needing conversion, and can be combined with minoxidil and retinoids like tretinoin for enhanced effectiveness. Minoxidil's efficacy may be reduced by COX-1 inhibitors, but using prostaglandin analogs like Latanoprost or Bimatoprost can help maintain its effectiveness.

Pyrilutamide shows promising hair growth results, but skepticism exists due to potential biases and lack of blinding in the study. Concerns about side effects and legitimacy of the product persist, with comparisons to finasteride and discussions on post-finasteride syndrome.

Topical Dutasteride is more effective than topical Finasteride for treating AGA in men, with fewer side effects. Mesotherapy with Dutasteride, administered every 3 months, shows promising results for hair regrowth and maintenance without daily routines or significant side effects.

The conversation discusses whether to use finasteride for hair loss, considering its role in inhibiting DHT and 5AR, which can affect brain function and mood. Some users report anxiety and depression from finasteride, while others do not experience these side effects and emphasize the importance of DHT for brain and prostate health.

AH-001 is a new topical treatment designed to degrade androgen receptors, targeting the root cause of androgenetic alopecia without the side effects of oral treatments like finasteride. It has shown a strong safety profile and good local tolerability in early trials.

The conversation discusses the delay in the release of a new hair loss treatment, Pyrilutamide, and speculates on potential safety concerns as a reason for the delay. It also mentions GT20029 as another future treatment option, with a release at least five years away, and touches on the avoidance of research chemicals due to uncertainty about their authenticity.

PP405 shows promise in treating severe hair loss, with 31% of users experiencing over 20% hair density increase in four weeks, faster than minoxidil and finasteride. Some users are skeptical about the results' significance and long-term efficacy.

Combining finasteride and dutasteride with activities that raise testosterone may increase the risk of side effects like gynecomastia, depending on genetic predisposition and hormone levels. It's advised to check hormone levels to assess the risk.

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.

Inflammation plays a significant role in hair follicle miniaturization and androgenetic alopecia, with treatments like ketoconazole shampoo, minoxidil, and finasteride being used to address it.
