How to penetrate my sad, dull low porosity hair?

I feel like all of the products just SIT on my head. Can someone please drop their routine? 🙏🏻 shampoo, conditioner, leave-in, gel 😭 I have 3b curls

I've been using cantu shea butter leave in for the past year and at first it was working (my hair was high porosity) but now I don't think it's doing much.
