This is THE best volmizing shampoo I have ever found and I have tried a lot. My first thought is that I've never ended up staying with the high end brands because you always get build up, no matter what they say. Same problem with the average brands. But I have to say, I've now been using Renpur Volumizing shampoo for a couple of months with no problems. I don't even use conditioner afterwards b/c its pretty gentle. My other favorite is Aussie Awesome volume.
