Maybe a good ol' fashioned clarify and DT? I just did that and I hadn't for a long time.
I did a vinegar rinse (pretty strong, left it on for a while) and then a homemade DT with avocado, banana, honey, condish and olive oil.
My hair really liked it.
I know it can get frustrating sometimes ... and growing out can be hard. Have you had a micro-trim/shape-up lately? Maybe that would give you a boost.
Maybe simplify your routine a bit for a while? I'm going back CG for a while again.
At any rate ... CONGRATS!!!
ETA: Nevermind - I missed the part about the trim in your post. D'oh!
