I used this EXACTLY as directed with NO noticeable difference in my hair!  I was advised numerous times by my hair stylist how well this works to give my hair some shine as well as tame the frizzies.  Nadda!  This is a very high-price item to give no noticeable results.  Please save your hard-earned money.  There are plenty of other more reasonably priced products out there that do a good job. I do not recommend this product.
