I don't like Miss Jessie's products at all. I think they are crap, so I'm not much of a help there, but it sounds like you might like Curl Junkie Repair Me!
It's very lotion-ey and it more moisturizing than most PTs. My hair almost tolerated it and that's saying something because I'm protein sensitive. I don't use it now, I sampled it, but I don't use protein treatments at all anymore. PTs don't really boost my hair, they just dry it out and add frizz/wiryness.
My daily RO conditioner has some oat protein in it and it's been very gentle to my hair.
