A lot of people including myself like to take the easy way out by trying to color their extensions without taking the hair out the bundle. The importance of making sure that the hair is not bundled up is so that all of the hair will get evenly dyed. Coloring the hair while its bundled up makes it hard to get each strand colored and it will end up giving it a more streak look. So make sure that before you color your hair unravel the bundle and I promise your hair will be evenly dyed and perfect !
