665 nm low level diode laser 808 nm low level diode laser laser hat laser scanner androgenic alopecia terminal hair density hair growth laser

TLDR The laser scanner device was more effective at increasing hair density than the laser hat in treating androgenic alopecia.

In 2017, a study involving 90 patients with androgenic alopecia compared the effects of a 665 nm low level diode Laser Hat and a combination of 665 nm and 808 nm low level diode Laser Scanner on hair growth. The patients were divided into three groups: one using a laser hat, one using a laser scanner, and a control group. The results showed a significant increase in terminal hair density in both the laser scanner and laser hat groups compared to the control group. However, the laser scanner group had a higher increase in terminal hair density (mean of 9.61 per cm²) compared to the laser hat group (mean of 9.16 per cm²). The study concluded that the laser scanner device was effective and safe for the treatment of androgenic alopecia.
