It is a common belief that laser hair removal only works on dark-colored hair, it’s not effective against light hair color. Well, there is no doubt that these treatments are more effective for a dark color, but if you can make a few changes, you can make it workable for light-colored hair.
An easy way to do this is to increase the intensity of the laser, this will let the device treat light-colored hair. Another way of treating light-colored hair is by implementing longer wavelengths as it treats all colors and melanin. This way, you can penetrate the hair without damaging the nearby tissues.
