Review (4/5): Great shampoo, but brittle bar is hard to use
First, the good: the shampoo itself is very nice, and doesn't weigh down my wavy hair. It lathers easily and rinses cleanly.
However, the bar itself is very brittle if you leave it to dry out between uses like you're supposed to. It shatters into multiple smaller pieces that make it difficult to use. I'd like to see Garnier make a thicker bar in a blockier, more uniform shape to offset this, as it's really the only drawback. I also use the Duke Cannon Field Mint shampoo puck as a clarifying bar, and I haven't run into the same issue with that one as I have the Garnier.
