Protective style within a protective style

I have a new challenge that is to wear my twist in a bun, the sides are twisted in to two large twist a pin up to the back, for a whole month I will try not to take the bun down until I wash and dc my hair which will probaly be sometime next week. I have HITF(hand in the fro) problem so this might be harder for me to do. I feel this would help reduce the little knots that i get in my hair and less tangles. No touching of the hair for a while.
