The conversation discusses the use of 5-alpha-reductase inhibitors like finasteride and dutasteride for hair loss in transgender women, particularly in relation to testosterone suppression. The original poster has been using dutasteride and is considering stopping it due to undetectable testosterone levels.

The user experienced erectile dysfunction from oral finasteride and is considering alternatives like topical high-dose finasteride, RU58841, topical Latanoprost, and oral Minoxidil. Blood tests showed changes in testosterone and DHT levels, and the endocrinologist advised stopping finasteride.

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

Doctors often prescribe finasteride for hair loss without testing testosterone levels. There is no need for such tests before starting the medication.

A 20-year-old with thinning hair has low vitamin D and normal testosterone. They are prescribed oral minoxidil and vitamin D, and are questioning if finasteride is also necessary.

The conversation discusses concerns about starting finasteride with low testosterone levels, with one person suggesting finasteride might increase testosterone and decrease DHT, and another advising to pay attention to thyroid-stimulating hormone (TSH) levels.

A user discovered they have naturally low DHT levels and is concerned about taking finasteride, which could further lower these levels. They are seeking advice on whether to proceed with the treatment given their hormone levels are within the normal range.

A 30-year-old male using finasteride for hair loss has high testosterone and estrogen levels but no side effects. He is advised to monitor hormone levels, consider dietary changes, and use additional treatments like vitamin D3, minoxidil, and dutasteride for hair growth.

A user shared their hair loss treatment regimen, which includes minoxidil, finasteride, ketoconazole shampoo, stemoxydine, and microneedling, and reported promising results. Other users complimented the progress.

The conversation discusses starting finasteride 1mg daily for hair loss and mentions a high baseline DHT level. Users comment on the unusually high DHT level and its potential causes.

Users discuss the effectiveness of low-dose topical finasteride (0.005-0.05%) for hair loss, often combined with minoxidil. Some report stable results or new growth, but it's unclear if improvements are due to finasteride or minoxidil.

A 19-year-old plans to use an experimental hair loss treatment stack including micro-needling, Minoxidil, Pyrilutamide, Ketoconazole shampoo, and other unreleased compounds like PP405. Users advise against using unverified treatments and suggest sticking to proven options like Finasteride, with some recommending topical application to avoid side effects.

Dutasteride may affect testosterone levels, leading to high ferritin and iron levels, which can cause hair loss. High ferritin might be linked to past heavy drinking or hemochromatosis.

The conversation is about using Vitamin B5, B6, and Biotin for hair health, with a focus on whether to take these supplements separately when using topical finasteride products. One user dismisses the effectiveness of multivitamins.

The user is on Finasteride for hair loss, taking 0.5mg daily, and plans to reduce the dose to 0.25mg while making lifestyle changes to lower prolactin, SHGB, and cortisol. They will retest in 90 days to assess progress and are open to advice.

Stemoxydine, a hair loss treatment, is reportedly discontinued, with some users suggesting alternatives like a rebranded version with resveratrol that may enhance Minoxidil. Some users express dissatisfaction with the discontinuation and question the product's value.

Topical dutasteride is considered more effective for hair regrowth with fewer side effects than oral finasteride. Users have mixed experiences, with some preferring topical applications for reduced side effects.

RU58841, combined with 5% minoxidil, helped reduce acne and hair loss. Users discussed using RU58841 cream for acne and shared experiences with other treatments like finasteride and dutasteride.

David Dobrik uses Minoxidil and possibly Finasteride for hair loss but applies them incorrectly. Users suggest he consider surgery due to his financial capability.

The conversation discusses using minoxidil, finasteride, spironolactone, and RU58841 for hair loss treatment. Users share experiences with these treatments, noting side effects and varying effectiveness.

A 21-year-old is using oral minoxidil, rosemary oil, saw palmetto, and pumpkin seed oil for hair regrowth but is advised to use finasteride or dutasteride for better results. The user is hesitant to use DHT blockers due to cost and is seeking advice on whether their current regimen is effective.

Creatine may increase DHT levels, potentially affecting hair loss in some individuals, but opinions vary. Some users report hair loss while on creatine, while others see no effect, especially when using treatments like finasteride, minoxidil, and microneedling.

OP is considering dutasteride mesotherapy for hair loss after experiencing side effects from finasteride. A user shared their experience, stating that the treatment was ineffective and costly.

Dutasteride mesotherapy is discussed as a potentially effective hair loss treatment with no sexual side effects, requiring less frequent application than daily pills. However, it is not widely popular due to limited availability, high cost, and skepticism about its effectiveness.

Finasteride users have mixed experiences with creatine; some experience increased hair loss, while others do not. Finasteride's DHT-blocking effects might counteract any DHT increase from creatine, but individual responses vary.

Panax ginseng, specifically a ginsenoside-enriched formulation, is suggested as a potential hair growth treatment alongside finasteride and minoxidil. The user is considering trying panax ginseng despite limited availability and evidence.
