To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This destroyed my hair. I have thin, colour treated hair but not damaged. I used this and it dried out my hair so much that it all started breaking off in chunks and what remains is dried out and damaged so much I’m afraid to run my fingers through it. DO NOT BUY!
The product that I received was the Dallas Thickening Shampoo, not the Biotin Thickening Shampoo. The photo on the packaging was different too. I haven't compared ingredients between the two, so don't know if it is actually an identical formulation. Otherwise, the product itself seems ok; I just feel like I was mislead, hence the three stars.
