How long after STOPPING finasteride did you start to lose hair again?

Was it like a 3-4 weeks or more like a few months?

I accidentally stopped my finasteride - traveled early November and forgot about it in my suitcase. Early December started losing hair. Didn’t realize what had happened until late December, when I restarted the finasteride.

I’m also on a weight loss journey so I’m trying to figure out if the hair loss was likely due to stopping finasteride or another reason.
