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.
After switching from finasteride to 0.5 mg dutasteride daily, the user experienced thinner hair but no shedding. They are considering continuing dutasteride and possibly using oral minoxidil, while also dealing with allergy-like symptoms possibly unrelated to the medication.
The conversation discusses the effectiveness and skepticism around topical dutasteride for hair loss, with mentions of combining it with other treatments like minoxidil and oral medications. Some users doubt its efficacy due to lack of independent studies and potential conflicts of interest.
A Dutasteride Simulator predicts serum dutasteride, serum DHT, and scalp DHT levels using models from research papers. It simulates various dosing schedules to determine steady-state effects and visualizes outcomes, including hair growth-related scalp DHT suppression.
The conversation discusses using very low dose topical finasteride to achieve specific serum DHT reduction percentages. It concludes that finasteride dosage increases linearly between 5-30% DHT reduction but requires exponential increases for reductions up to 70%.
