Hi there,
At two months post-op you you should be fully healed from your hair transplant procedure. A tattoo session to your arm will not cause harm to the grafts. Best of luck!
Hair goes through its intrinsic cycle of growth and will grow out gradually. It may take up to one year for fill growth. You ned to wait and see the final result.
Thea answer is to wait at least one month as your doctor advised. This works for FUE but not for Strip which requires at least 6 weeks for complete healing to occur.
