There are two goals of hair transplantation.

1. Natural Results

Natural results mean that it is undetectable to the human eye. No one will be able to detect that you ever had a hair transplant surgery done.

2. A Balanced and Harmonious Look

To achieve this, we should have the same volume of hair in all regions. This means that the donor site and recipient site both have the same density. A lot of hair transplant experts know that, because of illusions from the human eye, it is difficult for people to tell the difference between 50% and 100% density.

Based upon this knowledge, we only have to deliver 50% added density to a recipient site to achieve a look of full density. (However, this also depends on age, expectations, and the contrast between the color of the hair and skin, so some adjustments may be needed)
