Great OP! You'll play with your new 4 (wow!) formulas and see what your hair likes the best!
I like to test new (for me) CC by doing both cleanses with it alone, and using the same as CC as leave-in. If my hair comes out "too dry", I don't get discouraged and use spraying mist on the ends and a bit all over to "fix" dryness. I believe you have Mist in you BGT kit, OP.
Then, if some CC is not "perfect", try to combine it with the other and see what happens. Also Try to incorporate Six Thirteen, it does come with your BGT kit also. Add a pump or two to second cleanse. Or more, depending on your hair.
613 and TT are very "healing" for the hair, and gradually restore it's health. I try to use TT as my first cleanse all the time, because it is great for health of scalp as well. But nowdays, I have so many new CCs to try, unfortunately I am skipping this step in this routine lately, while checking my new ones.
Good luck to you with Wen!
