BUY IT !!!  You will be glad you did.
Undoubtedly the BEST shampoo I have EVER used!  I am in my fifties and have had scalp issues all my life. Now, problems with dry and brittle hair. I bought this shampoo just by chance. The product I had been using was temporarily out of stock and I just happened to see this, read a few reviews, and ordered it. So glad I did. My scalp psoriasis had lessened dramatically after 2 washings. My hair is actually soft and shiny again. I am getting complements on it. This shampoo is worth every penny it cost.
