Questions about Oral Dutasteride
What is Dutasteride?
Dutasteride is a 5-alpha-reductase inhibitor that suppresses DHT production. Unlike finasteride (which blocks only one of the 5-AR enzyme types), dutasteride blocks both Type I and Type II - acting as a more complete DHT suppressor at the root of hair loss.
Does Dutasteride regrow hair better than finasteride?
Dutasteride suppresses up to ~98% of circulating DHT (vs ~65-70% for finasteride), offering potentially stronger DHT blockade.
What should I expect in terms of timeline?
DHT suppression occurs relatively quickly after consistent usage, but visible hair stabilization or regrowth may take 3-6 months or more depending on individual response and hair cycle.
What happens if I stop treatment?
If you discontinue dutasteride, DHT production may resume - over time, this can lead to resumed miniaturization and hair shedding. Hair loss treatments like dutasteride are typically ongoing for lasting results.
