I have color-treated hair. As I've aged my hair has become more curly/frizzy and almost brittle (it was always thick and wavy) and, of course, some grey. My daughter introduced me to this product and I really liked how it 'settled' my hair, especially in high humidity. For now I've even stopped using my regular 'rinse out' conditioner. I couldn't find it locally for purchase so I was so happy to find it on Amazon.
