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.
Finasteride reduces scalp DHT significantly even at low doses, with 0.2 mg reducing it by about 55%, but higher doses like 1 mg and 5 mg offer only marginally more reduction. Users discuss side effects, with some experiencing none and others reporting issues like low libido, and they also mention using other treatments like minoxidil and dutasteride.
Dutasteride might be better for hairline due to varying levels of 5AR activity in scalps. Genetic tests can determine if finasteride is enough or if dutasteride is needed.
