ELOS – Cont.: Few studies have been conducted regarding the ELOS Dr. Neil Sadick conducted a studies in 2004 using the ELOS system observed an average of 48% hair removal in 18 months Slightly higher results with blond hair (52%) vs. (44%) white hair Discussion of Study This study found consistent results with Dr. Sadick’s studies RF has been used for over a century to treat the hair follicle, however the thermal effect is not conducted well in the hair shaft Electrical current created between the electrodes streams is concentrate in layer of 20 – 40 microns around the hair Discussion Cont.: The bulge area is important as well as the hair follicle in regards to hair regrowth Studies have shown that hair can regenerate from totally follicle-free skin RF does not need a chromophore to effectively treat the hair follicle RF properties permit negligible reflection or scattering of energy Light energies require a chromophore in the skin and permits scattering of energies. Discussion cont.: RF requires a conductive media (water) to RF enables a direct measure of the current and voltage on the electrodes delivered to the skin This study shows advances in technology for hair removal, however further research with greater numbers is advised Conclusion The ELOS system can be effectively used in reduction of blond hair.
