Nexxus youth renewal conditioner might be an option. it's $14 a bottle but it is silicone free (not all nexxus products are) and it has protein, but it is the very last ingredient in the condish so it is a very small dose. I think it smells like vanilla cake but it's not overpowering to me. I love the smell personally, but since you mentioned scent I thought I'd point that out lol
