I slept with this my hair last night, hoping to add needed moisture, but instead I got dry, straw-like hair which I can't wash away! Is the problem too much protein?

More importantly, what can I do to fix this?

Any suggestions are appreciated. I'm new to CG, and new to my own hair, in a way. I wore a pixie for years because I couldn't handle the curls and only recently grew it out.

TIA.
