When you were a loose natural, what did you use in your hair? You could use the same "stuff" in your hair. Don't use the JML stuff. While it smells good (LOL) it won't do anything for you. Also, retwisting every two weeks is too frequent. If you must twist, drag it out a little. Twisting every two weeks will lead to breakage/thinning down the line unfortunately.
You can just separate your locs at the root. You won't have that freshly done look but you can still style your hair and have it look nice. If I can find a youtube video showing how to separate, I will forward it to you.
