Can stress affect the results of a hair transplant?

This is an interesting question. Stress-related hair loss has been a subject explored by researchers for years and, in certain cases, individuals may see an increase in hair loss during times of stress. But it is unlikely that your hair transplant procedure will be affected by the stress and anxiety you've described. You may notice some loss of transplanted hair after your procedure, but that is a normal part of the hair restoration process. I would discuss these concerns with your hair transplant surgeon, but I believe it's fine to go ahead with the scheduled procedure.

In general stress can affect your physical well being.  This may include hair loss.  If you're concerned please contact your doctor.

Stress can impact the hair you have on your head, your native hair but probably not the transplanted hair. This is more true in men then women who have more stress related hair loss even in the donor area
