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.

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.

Salicylic acid can reduce the effectiveness of minoxidil for beard growth. Users discuss avoiding salicylic acid when using minoxidil.

Oral minoxidil may cause dry skin and dark eye bags but doesn't significantly age the skin. Topical minoxidil is toxic to cats, and some users prefer finasteride.

Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.

Pyrilutimide, a treatment for hair loss; it's effectiveness compared to other treatments such as Finasteride and RU58841; and some users’ experiences with the treatment.

Hair loss treatments, specifically the use of finasteride, microneedling and potentially oral minoxidil. People discussed their experiences with finasteride, its effects on sexual behaviors, as well as potential solutions such as tadalafil or using other growth factor signal peptides for hope in curing male pattern baldness.

The conversation discusses the potential of long-chain unsaturated fatty acids, like oleic and linoleic acid, as an additional treatment for hair loss, which may inhibit the enzyme responsible for converting testosterone to DHT and promote hair growth. Users humorously suggest using oils topically and discuss other hair loss treatments, but the main focus is on the science behind fatty acids and their role in hair health.

HMI-115, a newly discovered hair loss treatment that could potentially be effective for those with diffuse thinning and telogen effluvium. It is based on prolactin receptor antagonist signaling and has already undergone Phase I trials in women, with potential commercialization by 2027.

The conversation discusses the tension theory as a cause of male pattern baldness (MPB), suggesting that scalp tension and reduced subcutaneous fat layer contribute to hair loss. Treatments mentioned include Minoxidil, finasteride, microneedling, scalp massages, and Botox.

Hair loss treatments, specifically 5AR inhibitors, can impact neurosteroids and sexual health. The effects of topical fin/dut on tissue-specific DHT levels are unclear.

A user's plan to use Zix and topical finasteride (5AR inhibitors) for hair loss, followed by blood testing before/after. The user has suggested creating a fund to cover part of the cost of their blood tests. Replies to their post discuss the effectiveness of the treatments.

Researching and developing an effective local antagonist to block the androgen receptors for hair loss, as opposed to using DHT synthesis inhibitors that lower serum DHT levels. Several treatments such as CosmeRNA and Pyrilutamide are currently in development or undergoing trials.

Hair loss discussion includes finasteride intolerance and questioning if Pyrilutamide is an alternative. Pyrilutamide not commercially available, but may be tolerable if approved since it's not a 5aR inhibitor.

Lichen Planopilaris (LPP) is an autoimmune condition causing permanent hair loss and fibrosis, often misdiagnosed. Treatments include pioglitazone, topical corticosteroids, anti-inflammatory medication, and Jak inhibitors.

The conversation discusses the conflicting information about Zinc's effect on DHT and its role in hair loss. It mentions that Zinc can act as a 5AR inhibitor at high doses but may increase DHT if taken to correct a deficiency, and highlights the importance of nutritional balance for hair health.

DHT Itch and its link to balding, with various treatments such as finasteride being discussed. Members shared their experiences of scalp itch before and after taking 5AR inhibitors, and potential underlying causes such as seborrheic dermatitis were discussed.

A user is using minoxidil for hair loss and considering adding finasteride but their dermatologist advised waiting to see if minoxidil works alone. They are thinking about taking saw palmetto (serenoa repens) and biotin as alternatives and are asking for others' experiences and potential side effects.

The user has been using minoxidil for hair loss and is considering trying a compounded topical treatment with 0.1% dutasteride, minoxidil, tretinoin, collagen, and silicon, as recommended by a trichologist. They learned that dutasteride might be more effective than finasteride and are seeking opinions on the use of topical dutasteride.

A user experienced increased hair shedding and unchanged DHT levels after taking 0.25mg of finasteride for 47 days, leading them to increase the dose to 0.5mg. Others discussed varying experiences with finasteride, minoxidil, and the importance of measuring scalp DHT.

Whether using both Fluridil and Alfatradiol together could be more effective than either one alone as a hair loss treatment, given their different mechanisms of action.

The user tried Minoxidil without success, and Finasteride worked but caused sexual side effects even at a very low dose. They are seeking alternative treatments for hair loss as they cannot tolerate anti-androgens and are also in therapy for mental health.

A new hair loss treatment, KX-826, is being discussed as a stronger and safer alternative to RU58841 and finasteride. Opinions are mixed, with some users skeptical about its effectiveness and others considering it as part of their regimen.

The user spends around 200€ monthly on hair loss treatments, including Kx826, Alfatradiol, Minoxidil, Nizoral Shampoo, Stemoxydine, Tretinoin, and a Dermastamp. The total cost is approximately 220$.

The conversation is about the role of testosterone in hair loss and the effectiveness of different treatments. The conclusion is that DHT is the main culprit for hair loss, and finasteride has been proven to work long-term in maintaining and regrowing hair. Testosterone may have a minor effect, but it is not the primary cause of hair loss.

Topical dutasteride is suggested as a low side-effect treatment for hair loss, with a proposed dose of 0.025% 1ml/day. It is considered better than finasteride due to its even inhibition of DHT isoforms and lower systemic absorption.

Dutasteride has been used for 20 years with some hair thickness improvement but no dramatic regrowth. The user also experimented with minoxidil, tretinoin, and peptides like BPC 157 for potential benefits in hair density and quality.

Serum DHT is mostly inactive; sebum DHT is a better measure for hair loss. Users discuss using finasteride, dutasteride, and topical treatments like KX826 and RU58841 for better scalp DHT suppression.

Dutasteride raises scalp testosterone by 99%, which may not be ideal for those sensitive to all androgens. Some argue finasteride's balancing act might be better, while others believe dutasteride is superior for hair regrowth.

Quitting vaping significantly reduced hair loss for a user who was a heavy vaper and also taking finasteride. Some participants suggest nicotine's vasoconstrictive properties may worsen hair loss, while others share personal anecdotes of hair improvement after quitting smoking or vaping.
