research Androgenetic Alopecia: Overview
AGA is a genetic, hormonal hair loss treated with finasteride, minoxidil, and supplements, but new compounds are being developed.
research A Model for the Turnover of Dihydrotestosterone in the Presence of the Irreversible 5α-Reductase Inhibitors GI198745 and Finasteride
Both drugs lower DHT levels, with GI198745 being more effective.
research Pharmacokinetic Parameters and Mechanisms of Inhibition of Rat Type 1 and 2 Steroid 5α-Reductases: Determinants for Different In Vivo Activities of GI198745 and Finasteride in the Rat
GI198745 is more potent and longer-lasting than finasteride, potentially better for treating hair loss.
research Dihydrotestosterone and the Concept of 5-Alpha-Reductase Inhibition in Human Benign Prostatic Hyperplasia
Blocking the enzyme that turns testosterone into DHT can safely and effectively treat enlarged prostate.
research Novel Agents for the Treatment of Alopecia
New treatments for hair loss show promise, especially finasteride for men and a stronger minoxidil formula.

community Research Backed Dutasteride Simulator (Serum/scalp DHT included for all doses)
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.
community Research Backed Dutasteride Simulator (Serum/Scalp DHT included for all doses)
A dutasteride simulator predicts that daily 0.5 mg dosing results in higher DHT suppression compared to less frequent dosing. Twice-weekly dutasteride may be as effective as finasteride 5 mg, providing a balance between efficacy and ease of use.
community From the research study: "Dihydrotestosterone and the concept of 5a-reductase inhibition in human benign prostatic hyperplasia" - G. Bartsch, R.S. Rittmaster, H. Klocker (2002) in the "World Journal of Urology".
Dutasteride is a stronger 5AR inhibitor than finasteride and can significantly lower DHT levels. Reduced doses of dutasteride may lower side effects.
community Warning: finasteride to dutasteride switch
Switching from finasteride to dutasteride can cause significant hair shedding if done abruptly. It's recommended to overlap both treatments and gradually taper off finasteride to minimize shedding.
community Dutasteride actually has different half lives depending on dose
Dutasteride's half-life varies with dosage, and lower doses can be effective with fewer side effects compared to finasteride. Some users report different side effects with dutasteride and finasteride, and extreme dosages of dutasteride are unnecessary and potentially harmful.
