My favorite brand is Special Effects..  But Hot Topic doesn't carry it anymore.  So Raw is my next favorite.  As for color, any.  Right now I'm using Coal Blue.  But everyone says it looks purple. 

Live XXL :') I've had many hair colours My favourite was red. But now i back to my hair colour.

I like Manic Panic.

I use a brand called "punky color" I love it I would chose it over manic panic anyday. My favorite so far is ultra violet :>
