Query: Definatly not worth losing your hair over

My friends and I all decided to try out this product. I used the Wen shampoo 3 times and each time, I found a ton of my hair falling out when I had the product in an was combing it.A couple of my friends who have tried it also experienced a ton of hair loss.When reading other reviews, I see there are many other people that have had the same experience as us.Its too expensive and no product is worth losing your hair over.
