I have had long hair for a *long* time and I'm told frequently (by my mom) that she's surprised I still have it. My hair is fine in texture, stick straight and blond. It also can be very fragile and knots easily. I've used many high end products for hair, the last one I finished was Living Proof Full Shampoo, and that was $25 for 8 ounces. This Arcona Primo is 4 ounces, yet...here I am writing a review that its WORTH it. The lather was surprising, the scent is sublime but it was the results that blew me away. Soft, shiny, full swinging hair. I thought, well its a new shampoo, but the concurrent uses provided the same results. My hair is color treated on the top only a few times a year for even color. I will definitely repurchase this shampoo (but waiting for a sale). Oh, and at first I thought I would have to use a lot, since we don't have a water softener and our water is fairly hard, nope, a dime to quarter size was sufficient, and as stated above, I have long hair.
