That's too bad it doesn't work for some. I have used it for 5 years and still love it. I tried the actual Matrix Biolage brand and much prefer the GVP to it. I love that it has so many uses. For me, I've used it as a co-wash, rinse out, leave-in and deep treatment. What more could you ask for from an inexpensive conditioner?
