Since the most restless and troublesome locks seem to be the ones at the back of your neck I would perhaps try to super condition them perhaps with warm olive oil prior to your next washing. That way the oil will be gone but hopefully will soften the tangles.

Barring that I would definitely go with blonde dreadlocks. : )
