Congratulations on your hair transplant and thank you for your question, We instruct all of our patients to avoid vigorous activity after receiving a hair transplant for up to 6 weeks post procedure, depending on the method used; FUE or strip graft. Heavy lifting and straining can cause the scar associated with the strip graft technique to widen and ultimately become and unattractive, noticeable scar. Excessive sweating, over heating and an increase in blood pressure can also have a negative effect on the newly transplanted hairs, with both the FUE and strip graft techniques. I would consult with your physician and see what their post- operative protocol is regarding exercise after surgery.
