washing only with water
Dread Maintenance
I often just rinse ("wash without soap") a few times a week out of convenience. It takes a bit of time to mix together the baking soda and oils that I use, and then again to dilute the ACV for a rinse, and then make sure all of that is rinsed out at the end. Sometimes, I just want to get my hair wet, squeeze it out, and give the scalp a nice rub with some water to displace any built up oils or dirt.
While I wouldn't say ditching the cleansers all together is the best idea, in my personal experience using only water is a decent way to refresh your scalp and dreads.
