The 2.5-mg dutasteride dose was consistently superior to 0.5-mg dutasteride in promoting scalp hair growth. The 2.5-mg dose was also better than the 0.5-mg dose at suppressing scalp DHT (79%...
DHT inhibitors are good to decrease DHT in the blood, but not very much in tissues, especially in the scalp.

Estrogens are the best. Androgen blockers like bicalutamide and cyproterone acetate are weaker than estrogens, but stronger than DHT inhibitors.
