I wear a WNG daily, but I don't do a WNG daily, if that makes sense. Basically, I do the whole WNG ritual (wash, apply products, etc.) once a week on Sunday morning and then just maintain it throughout. I can't imagine wearing wet hair every single day.
As far as wearing hair in a loose style, I don't think I've had damage from it. I just make sure my hair is properly moisturized.
