What owners single out
Both buyers and critics flag hair loss as a significant concern with this shampoo.
In their words
“I love this shampoo! I was a bit nervous because it's described as "gently clarifying'" and thought it might be drying on my long, color treated hair. However, it's not drying at all. It's sulfate and paraben free, and has a really nice lather that leaves your hair and scalp feeling really clean without dryness. The packaging is a really pretty neutral color that's spa like.”

“At first, I really liked this shampoo. The scent was amazing, and it seemed to work well for the first couple of months. But over time, I started noticing more and more hair coming out every time I washed it. I originally thought it was just stress, but it kept getting worse, and that’s when I started getting concerned.”
