I'm in Virginia, where summer humidity is pretty icky, and I have had great luck with a bit of a rich leave in (something CJ, usually CJAO) and a cocktail of SS CEJ and SS FHG. I mix the two in my palm - they have to be mixed first, I can't get good results if I layer for some whackadoodle reason - rake and then scrunch in, and top with a teeny weeny bit of BRHG. I always have great hair when I use this combo in summer, YMMV.
