1. Do you treat the twists as you would your normal detangled hair when washing/co-washing? i.e wash -> deep condition -> LOC method.
My answer: Yes, I do. (Backtrack: "Twist Series: Washing & Matting".) After washing, I apply conditioner to my twists down to my ends. I let the conditioner sit for however long (15-45 minutes) and then rinse. When rinsing, it helps to squeeze my twists in order to squeeze out most of the conditioner. I then plop my hair to help it air dry and moisturize + seal.
If my hair is not that dirty and/or I want to preserve the "neatness" of my twists a little longer, I sometimes use this washing method instead. For this latter washing method, it is very important that I use thoroughly diluted shampoo rather than shampoo alone.
2. How do you re-do the twists you mentioned? Do you unravel, detangle, re-twist and then wash all of them or do you wash first then unravel and re-twist?
My answer: I wash them first, allow them to air dry to about 60-80%, then unravel and re-twist them. When un-raveling them, I also make sure to remove any shed hair.
