I was/am experiencing the same thing. My hair is 4b with looser 4a in the front and nape of my neck. My hair was sooo dry and my ends were crunchy

. It's growing nicely and I wanna keep up the progress. My BC 1 year anniversary was last month.... ! Yaaay!
I agree about switching up your DC. I used to DC every other weekend and now I do it every weekend. I did the banana and honey one weekend and that did wonders. I did a rhassoul clay mixed with AOHR another that was very cleansing. Then I use my fave DC MyHoneyChild Honey Hair Mask w/heat. I also spritz it miday with my own spritz of 100% Aloe gel, water, camelia oil, and EO's. This entire regimen has really helped. I also wrap it tight at night with a scarf, rather than loose in a satin cap, and try to manipulate it less. Before I add any type of hairdress cream I mist with moisture - that helps combat dryness ALOT. My fave moisture creams are: shea butter, I make my own shea, castor, aloe mix, and Quemet Burdock Root Butter Cream. Also I use lots of leave in, either Giovanni Direct or Darcy's leave in or good ol' heaven sent shea butter,
