I used to believe that only relaxed women were the ones who could not wet their hair that often. When I became natural, I used to wash and condition much more often. At first it was once a week, but as I started getting into going to the gym, it became once every day or every other day.
Now I know a bit better, so I try to wash 1-2x per week, and do a cowash if I feel my hair needs it. I do not need to be shampooing every day! I wet my hair every day, though, regardless of whether I am washing/cowashing or not. I realise I need to use less moisturiser this way, and for the thicker, butter-based ones, I can get it into my hair much easier.
