The model showed that randomness accurately describes individual hair growth cycles and that synchronization can cause large fluctuations not seen in humans.
Dutasteride takes 1-3 months to affect scalp DHT levels, not just a week. The prostate absorbs Dutasteride faster than the scalp due to different vascular networks and enzyme densities.
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.
The user "Turbulent_Mix_318" shared their progress pictures after 7 months of using finasteride, dutasteride, and oral minoxidil for hair loss. They did not experience any adverse effects except for increased hair growth in other areas.
The user has been on dutasteride for 4.5 months after switching from finasteride due to hair thinning, and is experiencing significant hair loss despite also using minoxidil and microneedling. Many responses suggest that dutasteride takes time to show results, often requiring patience for up to a year or more, and recommend not stopping finasteride abruptly to avoid shedding.
Dutasteride is generally considered more effective than finasteride for hair regrowth and thickening, despite some negative anecdotal reports. Users report thicker hair and better skin with dutasteride, and some believe negative reviews are due to advanced alopecia or impatience with the shedding process.
