You do have to cleanse your hair at least once every 1-2 weeks using a shampoo. Yes, there are different types of shampoos and you may prefer one over the next but do not omit shampoo from your routine completely. Co-washing is fine but you need to cleanse your scalp regularly.

Rinse well when you do shampoo your hair. A part of the problem with the drying factor of shampoo is that it is not rinsed out properly. I typically rinse shampoo at least three times.
Some naturals advocate for the use of purified water. They say that it promotes healthier hair and also help with getting over growth plateaus. Perhaps use purified water for your final rinse.
