Hydra Whitening Shampoo 33.8oz

My poodle’s white fur has noticeably less yellow after just two washes—the optical brightener really works. I also appreciate how far the concentrated formula goes since you mix it with water.

My golden retriever's coat looked so dingy after winter, but this shampoo's optical brightener actually made him look white again after just one wash. The 33.8oz bottle is a great size and the concentrated formula means it will last me forever since you dilute it so much.

The 10:1 dilution ratio means this big bottle will last forever, which is perfect for my two dogs. I’ve noticed less yellowing in the white fur after just a few washes, and the coat feels clean without being stripped.
