The user experienced subtle hair growth improvements using finasteride, dutasteride, and minoxidil over nearly three years, with notable progress at the temples. The front hairline shows quicker regrowth cycles, but the vertex and crown remain unchanged.
PP405 is a new topical treatment for hair loss, showing promise in trials but still requires finasteride for maintenance. There is skepticism about its effectiveness and safety, with concerns about needing finasteride to maintain results.
Tretinoin may enhance minoxidil's effectiveness for those not responding to minoxidil alone, but it could reduce efficacy for some who are already responding to minoxidil. Tretinoin requires careful use, including skin moisturizing and sun protection due to increased sensitivity.
The conclusion of this conversation is that the user "DuckSeasonCamelSeasn" found that consuming grapefruit juice prior to taking finasteride or dutasteride helped them become a responder to the medications and regain hair growth. However, there are warnings about potential risks and interactions with other medications, so caution should be exercised.
The user experienced increased hair miniaturization and shedding despite using finasteride, topical minoxidil, microneedling, and other treatments. They are considering more aggressive treatments or a hair system if no improvement occurs by the end of 2025.
