Without driving you nuts, the traditional protein ingredients are not found in the product you are asking about. However sometimes natural extracs like the Sea extract, Kelp extract listed in the ingredients act like protein.
So as always, it comes down to testing on your hair. In my signature are protein free products (minus suave coconu condish which has silk protein).
Let me know how it goes.
