L'Oreal Paris Elvive Total...
I have only used this as a leave and have yet to try it as a deep conditioner. Any time I find a product that is a deep conditioner but can also be left in as a leave. I leave it in. My hair is always soft and manageable while using it. So far every product that I have used with it has been able to pair with it very well. Meaning it doesn't leave a residue.
