I have very fine, fragile, color treated hair and this one, along with its conditioner, was a nightmare. I ran out of my usual L'Oreal Vitamino Color after relocating and was desperate to find an alternative locally. Upon using, the scent was nice enough but I knew I was in trouble after combing through my towel dried hair and seeing the mass of hair that came out in my comb after just 1 use. Having spent nearly $40 on the shampoo & conditioner, I have given it a few chances periodically and the same thing happens every time: masses of hair on my comb after washing. And not just a few hairs, we're talking major fall out. When I return to my regular routine, the hair loss stops. It's unfortunate b/c aside from this tragic aspect it seems ok - nice shine, not weighed down... Something in this my hair just hates, though. So it garners a Worst Shampoo Ever Used for the hair loss alone.
