I don't know about the crown and glory technique but I've worn kt's before. If I were you I 'd whip up the most moisturizing concoction you can think of and also grab a little wild growth oil. Dilute the wild growth oil by half with extra evoo. Carry a small bottle of the moisturizing spritz with you. Spray your hair (the region that includes your tresses) at least once during the day plus morning and night. Don't pull your hair too tight (into tight buns etc) Wear half up half down sometimes. Putting all of the hair in a bun puts a lot of pressure on the front.
They're so easy to do, I'd suggest you redo the front yourself. Fold the same hair in half, use your own hair as the centerpiece, cornbraid once or twice then divide your hair and twist it in. Don't pull tight. You might even want to put a clip at the base as you twist to keep it from pulling.
Moisture, moisture, moisture, moisture, moisture, moisture. This will make your hair thrive. Daily doctor, s-curl, asha's silk rose, oyin's greg juice (kicked up with a little extra glycerine, etc. All of these would be great. If you surge you can add a quarter of surge to your spritz and get the benefits without the itch. Acjazzes rosemary spritz is a good option too.
Or, of course, make your own.

eta: use the diluted wild growth oil to oil your scalp once or twice a week. just go down all the rows with the tip. try to do this in the evening so it has time to absorb.
