My hair is very dry at the back to the ends. I condition, but doesn't help. What am I doing wrong?

You must do deep conditioning or a hair masque at least once a week then because i too have that problem and have tope 3B. I use the Argan oil form Morocco deep treatment, it comes in a little packet. I use this after i regularly condition my hair for extra moisture. Also, once a week i use any of my shea moisture hair masques, (they are amazing).
