Hydra Retail Whitening Shampoo-10.14oz.

Our Cavalier's tear stains were driving me crazy, and these are noticeably lighter after just two weeks of washing. The oatmeal extract in it definitely helps, since his skin doesn't seem as itchy after baths, and the coat has a real glow now.

The oatmeal extract is a game changer—my white dog's chest fur actually looks brighter after just two washes, and the coat feels noticeably softer to the touch. It lathers up nicely and rinses out clean without that squeaky, stripped feeling.

After three washes, the yellow stains around her mouth are basically gone—the optical brighteners really do the work without any bleach smell. Coat feels softer and has that healthy bounce back, and the oatmeal extract seems to keep her skin from getting itchy like other whiteners did.
