Just based on ingredients listed I see that being an ok leave in for hair that is fine and high porosity, probably heat styled and/or color treated. That said, you won't know how it will work for you until you try it. But definitely alternate with something protein free just to be on the safe side.
4a/3c, fine strands, low porosity, medium density
