Review (5/5): For me-The only color retention shampoo that does what it says!
My colorist gave me sample sizes of this shampoo and compatible conditioner to try after I complained about my expensive color fading too quickly. It is super-duper concentrated! You need only a dime sized dollop to do the job. Smells great (the conditioner has a nice bracing minty/herbal fragrance..yum!) I swear by this formula. My color looks beautiful up to my next salon appointment. After spending beaucoup bucks on store brands...I have finally hit the mark with this product. Pricey..but it lasts for ages and ages!
