Protein preset hair repairer

I received this product free to try and I can't tell much of a difference in my hair from before I tried this product. It is to be applied once a week before regular shampoo/conditioning. It might look a little bit shinier, but not enough to say that I can recommend this. It doesn't leave my hair any healthier looking or any less tangled. I don't feel like it repaired any of the damage. I felt like it just added an extra step for nothing.
