Really great product. I've been searching for another to replace Pureology (As it is no longer the same formula I grew to love since Loreal bought the company) and this has been a great substitute. I have thick, frizzy hair. This gets my hair clean without over-drying. You do not need that much of the product, which makes it last a while. It also lathers quite nicely unlike similar shampoos. Overall, great experience - highly recommends for those who have thick, frizzy hair and do not wash more than 2-3 times per week.
