简要总结
This study evaluates the optimizing parameters of long pulse Nd:YAG Laser for reducing the size of hair shaft diameter of the donor for hair transplantation. All participants will receive long-pulsed Nd-YAG laser treatments with three different parameters at the occipital area.
详细描述
Since the beginning of hair transplantation era, hair transplant technique has been greatly improved to achieve the best natural looking of hairline and hair density. Most Asians tend to have large size of hair shaft at the donor area, which often cause unnatural look of the hairline at the frontal area after hair transplantation due to the contrast between the transplanted hair and the original hair.
The idea of reducing the size of the hair shaft in the certain part of donor area before being transplanted to the frontal hairline becomes appealing. This transection is being practiced extensively in the field of cosmetic medicine by using long-pulsed Neodymium-Doped:Yttrium Aluminum Gamet (Nd:YAG), a laser treatment for permanent hair removal and vascular lesions.
