Traditional, light-only based hair removal systems are not able to treat blond, gray, red, and white hair at all. This is because these hairs contain little to no melanin. However, the Comet also is able to use radiofrequency to destroy hair follicles, and radiofrequency is a “color blind” technology. Thus, the Comet is the only permanent hair reduction system on the market that is able to treat these types of hair. These hairs are still difficult to treat and total clearance isn’t feasible without a high number of treatments. However, roughly 50% clearance is a reasonable expectation with 6-8 treatments. With any other laser technology, clearance of these hairs is 0%.
