No hair expert here...but I love Kenra (chelating), Ion clarifying shampoo (Sally's Beauty Supply) and Nexxus Aloe Rid(clarifying poo)...the Generic from Sally's works too!!! Because of raved reviews I tried Baking Soda and I can say I really like the feel of my hair!
However, when I use Kenra I HAVE to follow up with a moisturizing Deep conditioner! ^^^^the other three I mentioned doesn't strip my hair like Kenra! But I love the feel of my hair after using Kenra and then deep conditioning!
