For hair transplantation surgery by Follicular Unit Extraction (FUE), surgical preparation is the same as that described in article 1, by using small punctures to penetrate the follicular unit grafts to extract and transplant into bald areas. In some cases, the follicular Unit Extraction (FUE) may not be the best method to use; the physician may use other surgical methods more suitable for hair transplantation, other than the method described in article 1.
