If you stop taking finasteride, hair loss will likely resume within 6 to 12 months, and any hair regrowth achieved while on the medication may gradually be lost.

If you’re dealing with hair loss, you’ve probably heard about finasteride. Originally designed to treat enlarged prostates, it’s now a go-to for many guys dealing with male pattern baldness. 

It works by lowering a hormone called dihydrotestosterone (DHT) in your body, which is linked to hair follicle shrinkage and eventual hair loss. By keeping DHT levels down, finasteride helps keep your hair follicles healthier. This can slow down hair loss and sometimes even kickstart new hair growth.

If you’re thinking about using finasteride, or you’re already taking it to help with your hair loss, knowing what’ll happen if you stop taking the medicine can help you make the best choice for your hair.

What happens if I stop taking finasteride?

When you stop taking finasteride, something important happens: the levels of DHT in your body start to rise again. Studies have shown that finasteride leaves the body relatively quickly, often within about 14 days. So, without finasteride to keep DHT in check, some guys notice their hair loss picks up right where it left off. 

If you do decide to discontinue finasteride, it’s a good idea to talk to your healthcare provider first. They can give you personalised advice based on your situation and help you understand what to expect. They might also discuss alternative treatments or strategies to help manage your hair loss effectively.

Ultimately, finasteride works as long as you’re taking it.
