I love my hair. It is still very soft and shiny. I am currently using the following Kerastase Nutritive products, available at Gadabout:

Nutritive Shampoo, every other day
Nutritive Conditioner, after shampoo
Reflection Chroma Protect, after towel drying, protects from styling
Nutritive Nutri-Sculpt, for styling

You will notice you will use less than the shampoo you find at the drug store. This shampoo is concentrated, so you will use a smaller amount.
I can’t go two days without at least wetting my hair. I shampoo every other day, and condition every day. Because I was shampooing every day, I was producing more oils in my hair, which was giving it the greasy look. Britney at Gadabout said that this will decrease if I start shampooing every other day. I’ll let you know how it works.
