I started with dyed dark reddish brown hair.
I divided my hair into four section. First, section your hair in half, so you have the left and right section. Then section the left and right hair in half again, by creating a part behind your ears. You will get something like this
I started applying the bleach to the ends of my hair working my way up and stopping about 1 1/2 inches from my roots. I worked one section of hair at a time started with the two sections in the back. I let the bleach process for maybe 15-20 minutes, or until it was just deeper than a pumpkin color. Then I applied the rest of the bleach to my roots, cover my head with a plastic bag, then waited until my hair was a pumpkin color. Then I rinsed, and shampooed my hair.
