I used it and noticed no effect. The shampoo felt more moisturizing than it did clarifying, which I take as a good sign (it has a very rich, creamy feel). It doesn't say anything about color treated hair on the bottle (just checked). I wasn't a fan of how it smelled, but I was really happy with how it made my hair "feel," so I never broke out my own bottle.
If you're picky about shampoo (which I know I usually am!) I would just pack what you're used to.
