What works for one persons hair may not work for another's.
Personally I love Nexxus, Alterna, Aveda, and Redken. My hair responds very well to all four of them and so those are my staples.
One of my sisters adores Keracare Humecto, but it never leaves my hair feeling very moisturized so I don't use it. Another does nothing but co-washes with Suave Citrus Smoothie and her hair is also beautiful.
