I prefer Humecto in the tub. If I recall correctly, Moisturfuse is only to be used to put intense moisture back into your hair (i.e after a relaxer).
I use it after heavy protein treatments because it makes my hair feel nice and soft again. When used on a regular, my hair became limp and mushy. Also, on their website, if you go to get the prescription for your hairtype, the Moisturfuse is recommended for natural hair and to restore moisture after a relaxer. For relaxed hair, they recommend Fulfyl which is a mixture of protein and moisture. I've never used the Fulfyl though, so I can't recommend that. I love Humecto though
