title: Blond hair removal using ELOS systems.
abstract: OBJECTIVE
  The aim of this study was to test blond hair removal using the ELOS system, which is optical energy and radio-frequency combined.
  
  
  METHODS
  Seventeen patients with blond hair were randomly selected from the Department of Lasertherapy, Medical Centre Maastricht, The Netherlands. The mean age of the patients was 57.4 years. The mean energy used per patient was 23.2 J/cm2 and the mean radio-frequency was 18.6 J/cm2.
  
  
  RESULTS
  A mean hair reduction of 57.4% was obtained with a mean of 8.5 treatments. There was a trend found between hair removal and the number of treatments. No correlation was found between the percentage of hair removal and age. Furthermore, there was no correlation between hair removal and the device's technical data. No major side effects were observed postoperatively.
  
  
  CONCLUSIONS
  This study showed that ELOS can effectively be used for blond hair reduction.
