Can a CT scan of brain cause hair loss? I've had hair shedding consistent with telogen effluvium afterwards.

I had a ct scan of my brain in June of last year. In late July I had hair shedding consistent with Talogen Effluvium. It’s been going on for a year now. Hair always grows back in its place but it’s weak and thin. Some of it it thick. It’s definitely doesn’t feel like my normal hair. I’ve also been under a considerable amount of stress with a personal issue so not sure. Wondering if there is a connection with the ct scan and if it does cause hair loss, will the hair return to normal state?
