I can't say one product in particular, but DEF using cone free conditioners and more natural based products. My hair has a natural moisture to it, when I wash out my conditioners it doesn't have a waxy/coney feel to it. I never have crazy tangling, my hair reacts positively to these products. It took me several years to realize it was products with tons of ingredients and cones that my hair doesn't like. It's weird, but I def feel the difference in my hair from using Giovanni, KBB, Elucence, Kenra... These are products I've used on and off for the past 5 years and I'd prob never be without them.
I think ... rather I know that going natural would really turn my hair around for the best too.
