What is the main difference between follicular unit extraction (FUE) and follicular unit grafting (FUG)?
The main difference is the extraction process of the follicular units from the donor region. FUG removes a long strip of skin from the donor region which leaves a permanent, thin scar at the back. The FUE method uses a tool to extract each follicular unit from the back individually which results in no linear scar. Both methods plant hairs into the scalp the same way.
