Nexxus Aloe Rid is my favorite clarifier. I have never tried baking soda and water so I can't compare them. I am not sure whether ACV is considered a clarifier. I've used it a couple of times after shampooing to remove shampoo residue, restore PH balance and close the hair cuticle.
Aloe Rid gave me brand new hair! My hair was super clean! I'm natural and was using it to prepare for a texlax. But I used Aloe Rid and flat ironed, and now my hair is relaxer straight--and still has body. I can't stop getting compliments! No frizz yet, either. I'm not sure if I am going to texlax anymore. Maybe if I want the looser curly look.
I would recommend it to all AA's, especially those who use cones and heat. It is well worth the money.
I really like Aloe Rid too! It does not leave the hair feeling stripped or dry at all!! Good product.
