SHR combines laser technology and pulse light to achieve almost painless results for the removal of most types of hair and is safe on all skin types. SHR is different from the traditional IPL and laser as it targets the hair germ cells and blood supply that feeds it. It does not rely sole(pigment) of the hair to effectively destroy the targeted hair. New research has shown that a slower, longer heating process is more effective for permanent hair reduction than high and short levels of energy.
