Justin Bieber is not a stranger to changing his look. He makes a lot of effort to change his look so that he will always look interesting to the general public and his fans. His natural hair color is brown but he is sporting a blonde hair color right now.
There are some people, usually, non-fans who seem to have forgotten what Justin’s natural hair color is but for true Beliebers who have stuck by him through thick and thin, they are aware. They like him no matter what his hair color is and no matter how many more tattoos he would add to his body.
