The conversation discusses the potential benefits of castor oil for hair thickening, with one user noting it may increase prostaglandin E2 and decrease PGD2. The original poster plans to take 1-2ml orally daily.

Pyrilutamide is believed to be more effective than RU58841 and 1 mg finasteride in treating hair loss, with no systemic hormonal effects and the potential to block more than 31% of scalp DHT. It may also antagonize scalp testosterone due to its action as an androgen receptor antagonist.

Latanoprost is discussed as a potential hair loss treatment, noted for its synergy with minoxidil and 5-AR inhibitors, but concerns include its effectiveness on scalp hair, cost, and potential skin darkening. Some users express interest in trying latanoprost or bimatoprost despite limited real-world evidence.

Experimenting with trestolone as a treatment for hair loss in an attempt to avoid DHT-related treatments such as finasteride and dutasteride, and discussing the potential effects of its receptor selectivity on the androgen receptors in the scalp.

Some users have experienced good hair regrowth with estradiol, cyproterone acetate, spironolactone, and bicalutamide, but these treatments may cause feminization and other side effects. It's advised to consult a doctor before using these treatments, as they can lower testosterone and have significant risks.

A 22-year-old with high estradiol levels is considering starting finasteride for hair loss. They have an upcoming endocrinologist appointment to discuss whether they should proceed with the treatment.

The user has been using oral minoxidil and dutasteride for hair loss without success and is considering adding topical 17α-estradiol, Pyrilutamide, Clascoterone, or cetirizine. They have confirmed low serum DHT levels and are exploring additional treatments due to genetic sensitivity to DHT and prostaglandin D2.

The conversation discusses the effectiveness of anti-androgens for hair loss, with a preference for topical treatments like RU58841 over oral options due to better scalp concentration and fewer side effects. Topical finasteride at 0.1% may provide some results, especially when combined with a topical androgen receptor antagonist like RU58841.

The conversation discusses using topical synthetic prostaglandins like Bimatoprost, Latanoprost, and cetirizine for hair growth. The user shares a link suggesting these treatments may be effective.

The user experienced high estradiol levels after using topical finasteride at 0.1 mg/day, which normalized after discontinuation. They are questioning if this low dosage could significantly impact hormone levels.

The conversation discusses topical androgen receptor blockers for hair loss, mentioning Clascoterone, Pyrilutamide, GT20029, and RU58841. Ketoconazole's effectiveness and application methods are also debated.

Pyrilutamide, a nonsteroidal antiandrogen drug under development for the potential treatment of androgenic alopecia. The conversation discusses its binding affinity to the androgen receptor and the timeline for possible availability after trials are completed in the United States and China.

PP405, developed by Pelage Pharmaceuticals, can reactivate dormant hair follicle stem cells and increase hair growth by 20% in eight weeks, unlike minoxidil or finasteride. However, skepticism remains about its effectiveness and availability, with concerns about funding and the timeline for broader access.

Pyrilutimide and CB-03-01, two treatments for hair loss, have similar clinical trial results despite different binding affinities to androgen receptors. Factors other than binding affinity, like the time a drug stays bound to the receptor, may influence their effectiveness.

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.

The user used 0.5 mL of 0.5 mg of Pyrilutamide for 60 days for hair loss, but didn't notice any hair growth. They shared their hormone panel results and are seeking advice on next steps.

Pyrilutamide and RU58841 are androgen receptor antagonists that block receptors without significantly reducing testosterone or DHT levels. Any indirect effect on androgen levels is likely negligible.

The conversation is about the potential impact of RU58841 on male fertility, specifically regarding sperm concentration, total count, and motility. The user is curious about the likelihood of RU58841 reducing fertility based on its mechanism of action and comparisons to similar substances.

The drugs RU-58841, Pyrilutamide (KX-826), Apalutamide, Enzalutamide, and Darolutamide, which are nonsteroidal antiandrogens (NSAA), potentially impacting male fertility. Pyrilutamide, similar to Enzalutamide, may have reversible effects on fertility.

HMI 115 did not work as expected for hair regrowth in humans, unlike in macaque monkeys. There is anticipation for further research on prolactin's role in hair loss, with expectations that pharmaceutical companies will likely solve this before universities.

Estrogen injections significantly improved hair growth, particularly on the crown, after stopping finasteride. Monotherapy with estrogen led to hairline improvement, but also caused sterility and potential feminization effects.

A user has been taking finasteride 1mg for 10 years without side effects but is concerned about high estradiol levels affecting weight loss. Another user suggests using estradiol blockers under medical supervision to manage the levels.

The conversation is about someone planning to start finasteride for hair loss and wanting to interpret pre-treatment blood panels to assess the risk of side effects like gynecomastia. They list various tests to measure hormone levels and other health indicators.

PP405, a topical LDH inhibitor, has shown to stimulate hair follicle stem cell proliferation in humans with moderate hair loss. They are advancing to more detailed trials this year.

The potential of lowering prolactin levels to regrow hair, with a reference to Bayer's drug HMI 115 which has been indicated as having this effect. Treatments mentioned include Minoxidil and Finasteride, as well as RU58841.

A user is seeking advice on a new topical hair loss treatment containing Minoxidil 3%, Finasteride 0.3%, Progesterone 1%, Hydrocortisone butyrate 0.1%, and Ketoconazole 0.5%. They are concerned about the systemic absorption of Finasteride and plan to do blood tests and a spermiogram before starting.

A user experienced increased estradiol, nipple tenderness, and ED after taking finasteride. They are considering dose reduction to mitigate these effects.

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.

PP405 shows promise in stimulating new terminal hair growth by activating dormant follicles, with no systemic adverse effects observed in a short-term trial. However, long-term efficacy remains unproven, and further trials are needed to confirm its potential as a hair loss treatment.

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.
