How about used both and like both.
Deva One C
- Detangles very well, I love the lemongrass smell, works great when left in
- don't love the fake peach smell as much as the lemongrass (personal opinion), doesn't detangle quite as well as One C but is GREAT as a leave in.
I think One C detangles better but I think Elucence is a great leave in. Depends on which is most important to you.
