People are discussing the anticipated release of PP405 phase 2a results, expected by the end of March, with some skepticism about its effectiveness. There is cautious optimism due to past experiences with similar treatments like Breezula, despite concerns about the lack of presentation at the AAD 2026 conference.

RU58841, a potential hair loss treatment, was not commercialized due to marketability issues and lack of long-term safety data. Concerns about its formulation and delivery methods further complicate its use.

Pelage is delaying the start of phase 3 trials for PP405 to 2026 due to necessary regulatory processes, despite having $120 million in funding. Users discuss the potential of PP405 for hair regrowth, with some expressing skepticism and others hopeful for new treatments like Breezula.

The conversation discusses the steps for microneedling, specifically differentiating between medical needling (0.5-1.5mm) and cosmetic needling (0.3mm). It emphasizes the importance of cleaning and disinfecting before microneedling, regardless of needle length.

A user experienced worsened hair condition after a PRP session and is considering stopping further sessions. They are using a Dermapen, electric massage, iron, saw palmetto, and plan to start minoxidil, but have had side effects with finasteride and are advised to consider dutasteride under medical supervision.

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.

A user is considering an extensive hair loss treatment regimen including oral dutasteride, oral minoxidil, topical finasteride, tretinoin, microneedling, keto shampoo, laser comb, and PRP injections. Suggestions include simplifying the routine, possibly increasing minoxidil dosage, and considering alternatives like RU58841, while cautioning against using estrogen due to potential side effects.

The conclusion of the conversation is that some individuals may experience a condition called reactionary hypergonadism when taking dutasteride for hair loss. This condition can lead to an increase in testosterone levels, which may worsen hair loss instead of improving it.

A user asked if anyone who didn't respond to minoxidil saw improvement after adding tretinoin. One person replied they saw hair growth on their hairline after using a combination of minoxidil, finasteride, and tretinoin, suggesting tretinoin may have made them respond to minoxidil.

The conversation is about the effectiveness of Redensyl for hair loss and whether to continue using Minoxidil alone, despite planning for a hair transplant eventually. The user also mentions using dermarolling, PRP therapy, and Nutrafol.
