Unlike other methods of hair transplantation, FUE hair transplantation does not leave a visible scar or in the donor area, nor in the area where the hairs are implanted. Nobody will notice you had a hair transplant, even if your hair is millimetert. The biggest tool that we currently use is 0.80 mm in diameter. The scars are so small they can only be seen under magnification or after shaving of the hair.
