You know, I should have thought about it more, but my dreads need WAAAAAAY more dye than my silky straight hair did.
I wound up with this weird calico effect for a while, then after two redyes I think I got ALMOST all of the stupid brown spots. Ughhh.
Common sense, you can come back to me any time you'd like.
Here's a before and after, though the afters are poor quality, because unfortunately I cracked ANOTHER camera screen. Ugh.
