Bright colors in your hair - awesome!
Bleaching the holy $#it out of your hair so you can have them - not awesome.
There is another way: colored hair extensions! woooohoooo....
You can have them in any color - bright or pastel. And they are real hair, so you can curl or flat iron them as much as you'd like. DOUBLE BONUS - When bright colors are put in your own hair, it fades everytime you wash it. Not so with these - SCORE!
