Finasteride vs dutasteride: What happens if I stop treatment?

Male pattern hair loss is an ongoing condition. Finasteride and dutasteride lower DHT while the drugs are active, but they do not permanently change your tendency to lose hair. Continued treatment is generally needed to maintain any hair benefit. Results vary.

After stopping finasteride, hair gained or maintained through treatment is commonly lost over the following months, often within about a year. Results vary. Dutasteride remains in the body much longer, but this does not mean its hair effects are permanent. The timing of renewed thinning can differ from person to person. Results vary.

Neither medicine usually requires tapering to prevent withdrawal. Still, speak with your prescriber before changing your routine. If you want to stop because of side effects, describe the symptoms and when they began. Some symptoms need medical review rather than waiting for the drug to leave your body.

Do not save leftover pills for occasional use or restart at a different dose without guidance. A licensed physician in your state can discuss whether another approach is appropriate and explain how to track your hair and symptoms after stopping.
