Concerns about hair loss after Gamma Knife treatment

Hello.

My wife recently had a tumor recur in her pituitary gland and underwent Gamma Knife treatment.

They say that they are losing a lot more hair than before, possibly due to the effects of gamma rays.

I didn't expect to lose this much after the procedure...

Does it stop falling like this? Or does it start playing again?

I'm still monitoring the situation... Should I provide separate care for it?

I've never had to worry about my hair like this before, so I feel completely lost about what to do.
