I recently tried Living Proof's hair serum... and I have to tell you, my hair has never been so easy to manage, I have a curl in my hair, with this serum, you only need a dime size, and it does your entire head of hair, you start with the ends, and work your way up, never apply it to your roots. It does exactly what is says, it tames, smooths and gives a nice shine to your hair. I would definitely recommend this product.
