Hair reduction: 48 months of experience with 800nm diode laser.
BACKGROUND
The goal of hair removal methods has always been permanent or at least long-term epilation. Laser technology and the axiom of selective photothermolysis allowed a new approach to this subject.


OBJECTIVE
The aim of this retrospective study was to determine the long-term efficacy of a solid state, 800nm pulsed near infrared diode laser system for the reduction of pigmented hair, and extending habitual hair plucking intervals.


METHODS
In 48 months 242 patients received 703 diode laser treatments on 477 sites. Treatment data and an anonymous patient questionnaire on data concerning undesired hair growth (e.g. predisposition, psychological aspects), and hair plucking habits were retrospectively evaluated to verify the benefit of 800-nm diode laser application for the reduction of excess hair.


RESULTS
After an average of 1.97 treatments (range 1-6) sufficient reduction of pigmented hair was achieved for a mean period of 8.1 months. The habitual hair plucking interval was raised from a mean of 3.69 days before treatment to 15.19 days after laser epilation. The procedure was tolerated by 81.4% without local anesthetics and well accepted by 82.55% of the patients.


CONCLUSIONS
800-nm diode laser assisted hair removal represents a safe and effective treatment option for the reduction of pigmented hair.
