The present invention is a dome helmet shape, low power diode laser is irradiated uniformly to the entire scalp through rotation and scan without staying in one place, further increases blood circulation activation to prevent hair loss and to maintain the hair root healthy will be. The front of the device consists of the power key, touch screen panel, status indicator and emergency switch from the left side, and the touch panel consists of the function panel for selecting the rotation angle, setting the irradiation time, turning the scan motor on and off, and stopping operation. . On the rear, a balance is mounted for balance between the power connection, positioning remote control and positioning drive at the bottom, and wheels for convenience of movement. The low power diode laser was placed in 8 equal parts (45 degrees each) inside the dome helmet covering the scalp, and the upper part was equipped with a scan type low power diode laser to irradiate the entire upper part without staying in one place. A guide was placed at the bottom of the dome helmet to rotate according to the roller operated by the step motor, and the position axis was fixed to the guide so that the dome helmet was rotated at an angle clockwise and counterclockwise. By adopting the rotation and scanning method, it is possible to transmit even energy by using the method of irradiating a wide range uniformly without focusing on one place when irradiating low power diode laser. In addition, a safety sensor was attached to the dome helmet to operate so that it was safe from the danger of laser irradiation. The low-power diode laser, which irradiates a wide range uniformly, performs phototherapy treatment to help the blood circulation of capillaries, thereby preventing hair loss, managing the scalp, strengthening the hair root, and strengthening the hair.본 고안은 돔 헬멧 형상으로 저출력 다이오드 레이저를 한곳에 머무르지 않고 회전 및 스캔을 통하여 전체 두피에 균일하게 조사하므로 혈액순환 활성화를 더욱 더 증가시켜 탈모 방지를 하고 모근을 건강하게 유지하는 탈모 방지기기에 관한 것이다. 기기의 전면은 좌측부터
