Hey :) I would suggest the awesome and vegan Camille Rose Naturals line. Her products are whipped and buttery, so you get the deep penetrating moisture of a butter with the light weight of a whipped cream. Perfection! My fav for wash & gos would be her Aloe Vera Whipped Butter Gel. Since your hair is low porosity, make sure to always apply product to wet/damp hair, you need as much moisture as you can get!
