create partial dreads from full length dreads

Hello! I've had dreads for about 4 years. I have straight hair, and my dread roots are about 1 inch from my scalp. My dreads are over 10 inches long.

I'd like to make my dreadlocks looser at the roots, creating a more "partial" dread look. Basically, I'd like my hair to be straight out from the roots for about 4-5 inches, and then the rest be dreads.

Any ideas on how i can create this look? Is there a way to loosen already locked roots (i know everyone is concerned with tightening them!). Is there a way to keep new growth from locking up?

Thank you!
LIsa W.
