An Integrative View of Mammalian Seasonal Neuroendocrinology

Melatonin's effect on aromatase expression is unclear, with studies showing both increases and decreases. Hormonal impacts are complex and inconsistent, similar to changing health advice on other substances.

High prolactin levels may contribute to hair loss, and some users suggest supplements like mucuna pruriens, vitamin B6, vitamin E, L-Tyrosine, L-Theanine, DIM, and Zinc to lower prolactin. Lifestyle changes to increase dopamine, such as reducing screen time and stress, are also recommended.

The conversation discusses using P5P (Vitamin B6) supplements to reduce elevated Prolactin levels and concerns about its potential effect on increasing DHT levels. The user is not currently using finasteride or any anti-androgens.

Hmi115, a prolactin receptor blocker, showed promise for hair growth, but results from Phase 2 trials have not been published. ABS-201, an AI-based analog, is expected to begin trials in December 2025, while commercialization of treatments like PP-405 is anticipated around 2027.

IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.

Poor sleep quality may affect hair growth cycles by disrupting the body's natural clock and stress hormones. The focus should be on improving sleep to support overall health, including hair growth, rather than relying solely on treatments like Minoxidil, finasteride, or RU58841.
