This is my first week wearing a half-wig. I did some big plaits in the back and the front of my hair is out (ear to ear). This week I co-washed the front a couple of times; did nothing to the rest of it. I had planned to do weekly deep conditioning treatments on entire head. Is this useful and/or necessary? Should I co-wash the entire head (which means I'd have to rebraid the back which would take more time....)
