Abstract

Background: This study aimed to evaluate the effectiveness of a combined set of low level diode laser scanner (665 nm and 808nm) on hair growth, and assessment of safety and effectiveness of a new laser scanner on hair growth treatment procedure in androgenic alopecia. Methods: 90 patients (18 to 70 years) with androgenic alopecia were randomized into three groups. The first group (n=30) received 655 nm red light using laser hat, the second group (n=30) received 655 nm red laser plus 808 nm infrared laser using a laser scanner of hair growth device (with the patent number: 77733) and the third group (n=30) received no laser as the control group. Results: Patients in laser scanner group had better results and showed a higher increase in Accepted Mterminal hair density compared with laser hat group (mean of 9.61 versus 9.16 per cm2). We found significant decrease in terminal hair density from baseline in control group (mean-1.8 per cm2, p<0.0001). Conclusion: Results showed a statistically significant improvement in the laser scanner of the hair growth group compared with laser hat and the control group. The study showed that treatment with new laser devise had a promising result without any observable adverse effects. © 2017, Journal of Cosmetic and Laser Therapy. All rights reserved.
