Background and Aim: Among destructive treatments for removal of unwanted hair, hair removal laser devices have widely replaced the old fashion methods due to their safety and effectiveness. The purpose of this study was to analyze the effective factors on treating unwanted hairs with a laser device.
Methods: This retrospective study, was performed on records of 122 patients who referred to a hair and skin clinic .Patients with hirsutism or other diseases were excluded. Hair thickness and color, skin color, number of laser sessions, age and sessions interval were evaluated. The collected data were analyzed by compeutering program SPSS version 21, analytic tests chi-square and logistic regression (P less than 0.05 considered meaningful).
Results: The average age of participants was 31.3±6.6 years. The average number of laser sessions was 5.4±2.1 and the most satisfying outcome was observed in dark hairs and more than 5 sessions (P<0.05). Multivariate logistic regression model illustrated that the number of sessions directly impacts the effectiveness of treating unwanted hair (P<0.05). Level below the rock curve and the sensitivity were 0.71(0.61-0.81) and 0.759, respectively.
Conclusion: This study showed that hair thickness and color, number of laser sessions are important factors on hair removal treatments by laser. For optimal outcome more sessions with longer follow up is recommended.
