Your hair sounds beautiful . If it is dry, have you tried any deep treatments? I am not currently using any storebought treatments, but I've had good results adding oils and/or honey to my usual conditioner and covering my hair with a plastic cap for up to an hour.
Also, you haven't given much detail about your hair routine, how often do you cleanse, do you use shampoo, what conditioners/leave ins, styling products are you using. . . ? This can all be contributing to your dryness, or at least, not helping to eliminate it.
