The reason I decided to invest in a nice shampoo was because my hair had begun to feel heavy and flat compared to it’s usual bouncy, full body. I don’t like to claim that I have curly hair but it’s definitely not straight, so let’s call it wavey. My waves were becoming stringy and dry, my roots were getting greasy faster then usual. So, I purchased the Shampoo and Conditioner and by the second wash my waves were back and my hair was full and bouncy once again. Will definitely repurchase. My roots are definitely back to normal again as well.
