I like the smell of the One Condition. Idk if it lingers, I don't remember and since I like it I wouldn't notice as much. But, I can say the no-poo smell does and it's ridiculous because I use such a teensy tiny bit only on my scalp *and* I use pretty smelling stuff over it. But its all I can smell for at least a day after. I'm guessing its the same for one-c.

I find it interesting that we all vary on whether we like the no-poo or one-c as far as smell yet no matter which one we like...we hate the other. I don't see anyone who likes both. lol
remember, with all advice or suggestions for your hair, YMMV!!
My hair:
2b wavy, medium texture, low porosity, med-high density. Protein finicky.
My routine:
Cleansing: DCNP, every 4-5 days (occasionally use CJ cleansers).
RO: CJSC, occasionally use JCDC
LI: KCKT or CJSL
Gel: KCCC, CJCIAB for 2nd day hair (sometimes third)

Heat is my friend: warm water rinses, steam caps, and diffuse dry. I love CLU cloths and my Denman.
