How much scalp dht does dutasteride 1mg, 1.5mg, and 2mg block? Finasteride/Dutasteride 2/14/2026
Dutasteride at 0.5mg blocks 50% of scalp DHT, while higher doses like 1mg and 2.5mg block more, with 2.5mg blocking up to 80%. Some users report better results with lower doses, and there's confusion about the effectiveness of different dosages on scalp versus serum DHT.

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 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 Alright, so what’s the best way to lower scalp DHT with the least impact on serum DHT?
Topical finasteride affects serum DHT less than oral forms, while dutasteride mesotherapy may impact only the scalp with minimal serum DHT effects. Oral dutasteride once a week is suggested to have few side effects.
community Is it sufficient to block scalp DHT topically, or is it also necessary to reduce serum DHT? (My Question is Elaborated Below)
Topical finasteride can be as effective as oral finasteride for hair regrowth with fewer systemic side effects, but precise dosing is essential. Combining oral dutasteride with topical finasteride is not recommended due to dutasteride's stronger inhibition.
community Is Scalp DHT more important than Serum DHT?
The user lost ground on oral finasteride and plans to switch to topical finasteride/minoxidil and microneedling. They are curious if topical treatments are more effective than oral ones.
