The P&P Hairline Laser: A Novel Hands-Free Laser-Assisted Hairline Device for Hair Restoration Surgery

Background: There are many methods to try to achieve symmetry in hairline design, for example, by using eyesight to adjust the drawing or by using measurements with a ruler, but it is difficult to do when there is no anatomical landmark to use. Here, we compare our hands-free, laser-assisted device—the P&P Hairline Laser—with the widely used original handheld laser device. Our goal was to achieve better symmetry by providing a fix for the difficulty in stabilizing the handheld device to the forehead while drawing the hairline.

Method: We invented a new hands-free, laser-assisted hairline device that can be used in several ways such as for placing a hairline (male or female), placing a posterior hairline, placing a symmetrical strip scar for FUT, and measuring scalp laxity. We have been testing this device on our patients (both men and women) at the DHT clinic since 2020.

Results: After using and testing this hands-free device in almost 100 patients, we are satisfied with the results and have concluded that the hairline that is traced and drawn by our enhanced device is very smooth compared with the one created by the original handheld device.

Discussion: The P&P Hairline Laser is convenient and lightweight and allows the surgeon to achieve a symmetrical hairline in less than a minute. It also can be used to draw the posterior hairline, eyebrows, beard cheek lines, and mustache; and it can be used to outline a strip incision symmetrically as well as measure scalp laxity. We feel by being hands-free and able to affix to the forehead, our device provides a benefit over the currently used handheld device.
