Tried Apex last night and I don't like it. I used the same exact products I use any other time except I swapped the Sabino for the Apex. My hair feels drier and it didn't do much for reversion. Now I didn't apply section by section so maybe that has something to do with it. I'm thinking about trying Cantu shea butter leave in before blow drying/flat ironing next time. It says it's a heat protectant.
