Triple Wavelength for Laser Hair Reduction: Parameter Selection and Optimisation of Results

ABSTRACT Background Triple wave hair removal is an advanced method for achieving permanent hair reduction which has always been challenging. This technique combines the benefits of three different wavelengths of laser light to target a broader range of skin types effectively. This study employed three different equipment. Aims To establish the efficacy of triple wavelength hair removal in various skin types, sites and type of hair. To give importance to parameter selection and various techniques to be employed in various situations to achieve permanent hair removal. Patients and Methods This was an Investigator initiated, two center study of female's patients with hirsutism above age 18 years with skin type III−V, areas included are face, chin, chest and others between the period of August 2017 to February 2024. Results The amount of hair reduction was assessed using the physician GAIS (Global Aesthetic Improvement Scale) score: No results 0% reduction, Poor 0%−25% reduction, Average 25%−50% reduction, good 50%−75% reduction, and excellent 75%−100% reduction. Patients who completed minimum of four to maximum of six sessions were included in the study. An excellent reduction in 80% of the treated patients and good reduction in 15% of treated patients was observed. Conclusion This current study shows that a synergistic combination of three diode laser wavelengths used for hair removal is effective and safe to use in subjects of all skin types for facial and body hair and is an alternative in treatment of patients who responds poorly to diode wavelength.
