About this study
Official title: Optimizing Parameters for Long-pulsed Nd:YAG Laser for Reducing Hair Shaft Diameter at the Donor Area for Hair Transplantation
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Long-pulsed, 1064nm Nd-YAG laserDevice
This long-pulsed Nd-YAG laser is commonly used for laser hair removal and vascular lesions, but in this study it is used to reduce the size of the hair shaft at the occipital area.
| Study group | Role | What they receive |
|---|---|---|
| Long-pulsed, 1064nm Nd-YAG laser | Experimental | All participants will receive long-pulsed, 1064nm Nd-YAG laser treatments with three different parameters at the occipital area. Receives: Device: Long-pulsed, 1064nm Nd-YAG laser |
What is being measured
The primary outcome is the main question the study is designed to answer.
Evaluate the changes in hair density at the treated sites.
Evaluate changes in hair density at the treated sites following long-pulsed, 1064 Nd-YAG laser sessions every 8 weeks or until the treatment endpoint is reached before or at 24 weeks.
Measured: 24 weeks
Secondary outcomes (1)
Evaluate the changes in hair diameter at the treated sites.
Evaluate the changes in hair diameter at the treated sites following long-pulsed, 1064 Nd-YAG laser sessions every 8 weeks or until the treatment endpoint is reached before or at 24 weeks.
Measured: 24 weeks
