I 2nd (or3rd) the DT. When mine is looking frazzled, I'll even leave it in over night wrapped in a plastic cap and a towel (I have some of those turban ones). Actually, I was pleased with how my hair came out that I'm doing it more. Saves time in the morning as all I have to do is rinse.

I don't know much about protein though.

Good luck!
