Everything about this product is a win for me. First off, it is extremely affordable, one bottle lasts me 1 and 1/2 months. Then, it basically is one solution for all of my hair and scalp problems. I have dry, damaged, frizzy hair and my scalp flakes from time to time. This formula banishes flakes for good, and the 2-in-1 formula does a wonderful job conditioning my hair. Overall, this is a total knockout of a product because one product can solve all my hair problems, plus I save money. I've been using this shampoo on and off for almost 10 years now, and it is definitely one to stick with. Effectiveness This shampoo transforms my flaking scalp, making it completely dandruff free. This product also does a great job restoring moisture to my hair, reversing all its damage, and making my once impossible to manage hair into shinier, healthier, and smooth locks. I absolutely love the results I get from this product because it is basically a solution for all my problems. Scent This product has an unidentifiable sent, but is definitely not unpleasant. I love it too!
