PP405 from Everychem is likely fake and potentially harmful, with concerns about its stability and the risk of using the wrong MPC inhibitor, which could damage hair follicles. The real PP405 was studied under strict conditions, and DIY attempts are discouraged due to unknown formulation and quality control.
Finasteride is prescribed at 1mg because it is FDA-approved and proven effective, despite evidence that 0.2mg may similarly reduce DHT. The 1mg dose is more effective for hair growth, and lower doses are less available.
Low doses of dutasteride are as effective as higher doses for hair regrowth, with fewer side effects. Users find success taking it 2-3 times a week instead of daily.
A 36-year-old achieved significant hair improvement and stability over 26 months using oral finasteride, minoxidil foam, microneedling, and ketoconazole shampoo, with no side effects. Patience and consistency were crucial for increased hair density and reduced shedding.
The user has been using oral dutasteride and minoxidil for over a year without regrowth or stability, and hair loss continues. Suggestions include checking for inflammation, considering a scalp biopsy, and trying microneedling, topical anti-androgens, or a hair transplant.
