Could Short Term Stress Cause Hair Problems?

I had a stressful 3 to 4 week period after a breakup with my girlfriend of which I am totally back to a normal stress free life. Will such short term stress do anything to my hair in regards to it falling out or changing its texture? It looks ok but just wanted to make sure that I didn’t do any damage.

I am 43 years old with a pretty good set of hair on me and have been taking finasteride as a precaution for the last 2 years.

It’s possible that you could see a classic case of telogen effluvium (stress-induced hair loss).
