My hair turned white

 I’m in my mid 20s and I got a hair transplant done 6 weeks ago.  I have started to notice a lot more white hair on my head after the transplant. Significantly more than before.  Am I just aging? Or have the hairs temporarily turned white as a result of the physical trauma of the surgery?

We have performed over 17,000 surgeries over 31 years and I don’t remember anyone’s hair turning white immediately after a hair transplant.  I have seen significant changes in hair texture, a few men developed kinky hair but not white hair.
