TWIST-1 gene's role in hair loss and potential as a treatment target. Inhibiting TWIST-1 may prolong hair growth and reduce hair follicle sensitivity to DHT.

Dutasteride at 0.5mg blocks 50% of scalp DHT, while higher doses like 1mg and 2.5mg block more, with 2.5mg blocking up to 80%. Some users report better results with lower doses, and there's confusion about the effectiveness of different dosages on scalp versus serum DHT.

The user added P5P (vitamin B6) to their shampoo to reduce scalp itch, which improved significantly. They have been using finasteride for hair loss but are exploring additional treatments like topical antiandrogens and prolactin inhibitors.

The conversation is about whether it is safe to take Xeljanz, a JAK inhibitor, while also taking finasteride for hair loss. The concern is that Xeljanz weakens the immune system, which could be risky.

People are discussing their reactions if PP405 fails in phase 3 trials, with some expressing skepticism and others holding onto hope for future treatments like GT20029 and Breezula. Many mention continuing with existing treatments like minoxidil and finasteride, while others express disappointment and consider alternative solutions.

Chime Biologics and Hope Medicine are speeding up the launch of a first-in-class antibody drug, HMI-115, for endometriosis and androgenic alopecia. The treatment involves a series of subcutaneous injections, has shown promising results in phase 1, and continues to promote hair regrowth even after the treatment is stopped.

Switching from finasteride to dutasteride may be more effective for hair regrowth due to dutasteride's stronger enzyme inhibition, but combining both drugs could enhance results. Some users report better outcomes with dutasteride, while others recommend a gradual transition to prevent potential hair loss.

The conversation concludes that finasteride, a 5α-Reductase inhibitor used for hair loss, does not impair cognition either short-term or long-term. It suggests "brain fog" is not caused by the medication.

The conversation discusses using non-denatured ethanol for RU58841. Treatments mentioned include Minoxidil, finasteride, and RU58841.

Pyrilutamide's effectiveness is questioned due to overstated claims and previous trial ineffectiveness, with some users opting for finasteride instead. Despite skepticism, some consider adding pyrilutamide to their regimen alongside treatments like bicalutamide.

The potential stability of pyrilutamide in a mixture with water, and how it could be used in combination with Minoxidil and Finasteride to treat hair loss.

Topical pirfenidone is highlighted as an effective anti-inflammatory and anti-fibrotic treatment for hair loss, particularly in addressing perifollicular fibrosis, which may enhance the effectiveness of standard treatments like finasteride and minoxidil. The user also uses calcipotriol, MCT oil, ciclopirox shampoo, and benzoyl peroxide shampoo as part of their regimen.

The conversation discusses whether oily scalp and sebum can hinder the absorption of topical hair loss treatments like Minoxidil and Finasteride, even when using tretinoin. The user is skeptical about the effectiveness of these treatments due to their oily scalp condition.

Elevated liver enzymes were reported from taking finasteride and minoxidil. The doctor advised stopping oral minoxidil and taking finasteride every other day.

The conversation discusses the effectiveness of a "Hair growth complex" pill, with skepticism about its ingredients like saw palmetto and anagain. Users suggest saw palmetto may help slightly with DHT-related hair loss, but it's less effective than finasteride or dutasteride.

The user applied 0.005% topical finasteride, minoxidil, tretinoin, caffeine, and ketoconazole shampoo for four months but saw no hair regrowth. Some users suggested increasing the finasteride dose or trying alternative treatments like clascoterone, pyrilutamide, or RU58841.

PP405 is a potential hair loss treatment, but its safety and effectiveness are uncertain. Users advise caution and suggest waiting for more data before purchasing unverified versions.

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

Saw palmetto and pumpkin seed oil are generally considered ineffective for hair regrowth compared to finasteride and minoxidil. Users report that finasteride, minoxidil, and sometimes dutasteride are more reliable for maintaining and regrowing hair.

A 25-year-old is considering using saw palmetto for hair loss due to fear of finasteride side effects but is concerned about its effectiveness and cost compared to finasteride. They are seeking advice on whether saw palmetto has similar side effects to finasteride and if it's truly effective or just a placebo.

The conversation discusses that dutasteride may be more effective than finasteride for frontal hair loss due to higher 5ar Type 1 enzyme activity in that area. Some users question the validity of this information, while others confirm it with additional sources.

PP405's phase 2a trial results were presented, focusing on safety and pharmacokinetics, with a future meeting planned to share the full dataset. The trial includes a randomized controlled portion and an open-label extension, with no indication of phase 2B completion.

Hope Medicine's announcement of the HMI-115 Phase II clinical trial for androgenetic alopecia in China; other related trials have been conducted or are ongoing in different countries, including Australia, US, and Europe. There is speculation that the product may be accepted across borders without additional testing.

The user is concerned about the interaction between dutasteride and ketoconazole, leading them to stop using ketoconazole shampoo, which has resulted in an oily and painful scalp. They are unsure whether ketoconazole increases or decreases the potency of dutasteride.

Caffeine is not a proven DHT blocker and does not effectively treat hair loss. Minoxidil, finasteride, and RU58841 are more reliable treatments.

Minoxidil and caffeine are discussed for hair loss treatment. The user questions the logic of combining them due to their opposing effects on adenosine receptors.

A sugar gel called 2-deoxy-D-ribose (2dDR) shows potential for promoting hair regrowth by increasing blood supply to hair follicles, similar to Minoxidil, but its effectiveness in humans is unproven. It may benefit those who don't tolerate Minoxidil, but it is not a replacement for treatments like Finasteride or RU58841.

Excessive sugar consumption may contribute to male pattern hair loss by increasing androgen sensitivity and insulin resistance, but genetics play a significant role. Treatments like minoxidil and finasteride are suggested for managing hair loss, while reducing sugar intake and maintaining a healthy lifestyle may help mitigate its progression.

Eucapil is discussed as a potential hair loss treatment with some believing it to be effective, though its efficacy compared to finasteride is debated. It is considered an anti-androgen treatment, often used alongside other treatments like minoxidil and finasteride, but lacks independent studies to fully support its effectiveness.

The conversation discusses the potential for high doses of dutasteride to completely inhibit scalp DHT and speculates whether this could cure baldness when combined with a topical antiandrogen. Specific dosages mentioned are 0.5 mg reducing scalp DHT by 55% and 2.5 mg by about 79%.
