Does argan oil work as a deep conditioner?

I want to deep-condition my hair, I've tried hair masks and they haven't done anything so I am considering argan oil. Has anyone tried this and can share their experience with it? How long should I leave it in for? Do I put it on dry or damp hair?

For context, my hair is wavy-straight, medium thickness, and has highlights. The top of my hair, where it's grown out and is my natural color, is soft, but my highlighted sections, and especially my ends, are kinda frizzy and could really benefit from deep moisture.
