The half-life of Dutasteride is commonly stated as around 5 weeks, but some sources suggest it is 170 hours for men aged 20–49, with further information indicating it varies from 3 days to 5 weeks depending on the dose. The user is seeking clarity on these conflicting figures.
The discussion revolves around the frequency of applying topical finasteride for hair loss treatment. The main question is whether applying it every 4-5 days could still be effective, given that its half-life in the scalp tissue is 5-6 days.
This conversation discussed the potential for a hair loss treatment alternative to minoxidil, with many users debating the economic and health implications of such an option. Some suggested that finasteride could be used as an alternative, while others argued that this would ultimately not benefit pharmaceutical companies due to their reliance on planned obsolescence.
The efficacy of taking 1mg finasteride three times a week instead of daily for hair loss, with some users arguing that it is just as effective because finasteride has a long half-life in the scalp tissue and lower doses have been shown to be effective. Other users suggest experimenting with various treatments such as minoxidil and finasteride to achieve best results.
Taking dutasteride daily at higher doses results in more effective DHT suppression compared to every other day dosing, due to its dose-dependent nature and long half-life. Even at lower doses, dutasteride is more effective than finasteride for hair loss.
