I think you should switch to a different low poo. Seems like those deva products have mixed results. Not everybody's hair likes them. Or you could clarify more often. I recommend a tea tree oil massage treatment though if you want to regulate sebum. You could also try putting some in your deva low poo or your co wash of choice. It's good for oily or dry scalp. I try to do the scalp treatment at least once every two weeks even though my scalp was pretty normal before CG and now after.
