I was a bit skeptical about all of the claims with this product and gave myself a few months before I wrote a review. This product delivers. My hair loss has diminished tremendously. Probably about a fraction of hair loss compared to a few months ago and my hair is full and shiny. Very happy with the product. At first it seemed pricey but the product goes along way and is healthy for my body. I highly recommend giving this shampoo a try. Very worthwhile investment.
