You might be sensitive to the cone in the two conditioners. I use a non sulfate poo, no poo, low poo or cream of nature once or twice a week.
I have to do that for just regular ole no protein no cone conditioner buildup too. My hair sucks things up and won't let go.
If I"m having days of crappy hair I shampoo with a no sulfate, if that doesn't work I do vinegar, and if it still is awful or I need a good hair day gauranteed then I just shampoo and do a DT.
Unless you're in a state that's still warm and humid I bet you need a heavier conditioner now.
Even OneC lately isn't doing it for me. I've been using REgis olive oil conditioner and then the Curl junkie hibiscus and banana butta leave in. It's weird because usually I don't need a thick conditioner but I have the heat on and it hasn't rained for about a week
