Do you know a leave in without any protien in it?

[MuslimahTresses]

I'm trying to perfect my roller set but I can't. Each time I've tried I gor brakage afterwards so I think it's becasue of my leave in. I've tried Lacio Lacio and Giovani Direct so far and I still get the breakage after it dries. I don't wanna give it just yet so I guess I'll try another leave in.
Any suggestions?
