I love PTR skincare, so I was curious about trying their line of hair care (for blondes, brunettes and redheads). The shampoo is deep golden brown in color to 'enhance' brown tones, though I'm not sure that it makes much of a difference (perhaps if not very thoroughly washed out it may stain light pillow cases though). The ingredients are pretty basic and not so good in terms of chemical content, and it seems to perform more or less like an average drugstore shampoo. I'll finish the bottle, but will stick to PTR skincare from now on.
