First, have you tried Fig instead of Bamboo Green Tea or 613? I can't use Bamboo Green Tea at all because just looking at it seems to dry my hair out. 613 is a great treatment, but it has a higher level of protein than other formulas and too much protein can dry hair out.
If you haven't tried Fig, I'd go there. Fig is my staple for my dry hair that tends to frizz. You may also want to look into the LOC method, which is Leave-in, Oil, and a Cream. I use WEN as my leave-in, a WEN oil (you can also use argan, coconut, sweet almond, or whatever oil you love), and then Shea Moisture Coconut & Hibiscus Curl Enhancing Smoothie as my cream. I also cheat some and add Curl Keeper, by Curly Hair Solutions, after the oil and before the Smoothie. I found that when I skipped this step, my hair frizzed a lot more often.
When I use Fig for every wash, my hair doesn't get dry. If I stray from Fig, the dryness creeps in (or smashes in like the Hulk if I use Bamboo Green Tea.)
