Good smelling lightweight oils that don't cost a bomb

I love oiling my hair. It has always worked for my hair health, and I champi my hair 2-3 times a week. I am okay with using whatever oil for champis, because I look at it like a treatment and don't leave it on for more than 1-2 hours before washing it off, so I am okay if it is heavy or light.

But I also like using lightweight oils to lock in my hair creams and gels post wash and do daily scalp massages. For these two things I prefer having a lightweight good smelling hair oil. Currently using Inde Wild champi hair oil that was gifted to me, and it smells divine and texture is nice and light. But it also costs a bomb, so I am here looking for suggestions that can be more sustainable for regular use.
