The only condition I know of which can cause
rapidRapid shallow breathing hair loss and regrowth of white hair is alopecia areata. This is a rather
commonCommon cold condtion whose cause is unknown. The body's immune system seems to be attacking the hair follicles, but no one knows why. Often, the hair grows back, but sometimes it's white when it does. The color may come back but it isn't certain it will. Treatment options are of limited use.
I am sorry for being so vague, but that is the way things are with this condition. You might check out the website: http://www.alopeciaareata.com/.
One thing for sure: this has nothing to do with the injury or the procedures. You are entitled to be skeptical of this coincidence, but coincidence it is. (I know that "stress" is often balmed, but that's just speculation.)
If I were you, I would see a dermatologist to get a definitive diagnosis, and look into the treatment options. In the meantime, you should at least consider dyeing your hair.
Best.
