Dip Dyed Hair

For about a couple of months now I have been wanting to dip dye my hair, and my mother is going to allow me to do it! I've been thinking about doing either a medium blonde or a caramel blonde. Maybe I can do both and make it more of an ombre type of hairstyle. I'll be sooo excited when my mom allows me to do this to my hair before school starts in late August...I CAN'T WAIT!!!
