Predicting the Therapeutic Results of Unwanted Hair Growth with the Alexandrite Laser Device

Abstract

The growth of excess hair on the chin, under the neck, near the navel, around the chest, etc. is one of the main disorders that both women and men face. The best, most efficient and least invasive way to remove thick and dark hair is to use a laser. It is important to check the effectiveness of laser in removing unwanted hair after treatment sessions. In this study, the treatment of unwanted hair in the armpit or thigh area in 14 patients was investigated. The participants with skin type I and III were aged 27-37 years and were treated with 755 nm alexandrite laser. Examination of each area (armpit and thigh) was done with a camera system specifically to count the number of hairs at 1 and 3 months after the treatment period. In this study, Monte Carlo modeling was used to estimate the density of excess hair remaining after treatment sessions, and the results showed that the number of excess hair decreased both by Monte Carlo method and manual counting method, and the accuracy rate of the simulation was 75%.
