Girl, me neither!
It's got hydrolyzed silk in it:
Ingredients: water/eau, stearyl alcohol, cyclopentasiloxane, cetyl alcohol, stearamidopropyl dimethylamine, rubus idaeus (raspberry) juice,
hydrolyzed silk, dimethicone, glutamic acid, fragrance/parfum, benzyl alcohol, citric acid, sodium chloride, edta, propylene glycol, dmdm hydantoin, red 33.
But it's never acted like a protein in my hair. I was applying it daily for a few weeks, and got no hardness or crunchiness. Just moisture. IMO, just because it has protein in it doesn't make it a protein product. It has more smoothing and conditioning agents in it than strengthening ones, so it's still a moisturizing product. After all, formulation and ratio of ingredients is important too, not just ingredients themselves. But I digress.
To answer OP's question, I'd say to just use what your hair likes. If it likes the LTR, then keep using it. If your hair hasn't been reacting so well to it, then try switching to another moisturizer.
