Just as great as I was told it would be!

I used this product like it told me for super damaged hair, so for 6 consecutive washes I applied it. It did wonders allowing the cuticle of my hair shaft to close. Since then I've been using it 1 to 2 times a week and its continued to allow my hair to look and feel so much healthier. I like the product so much I went back and got the oil to pair with it and I love that as well.
