Vedco's Micro BP Shampoo is a follicular flushing shampoo designed to provide long-lasting relief to your dog, cat, or horse. The shampoo's encapsulation system produces a slow release of ingredients, providing relief long after their bath is over. The small particle size is designed to facilitate the targeted delivery of benzoyl peroxide onto the skin and into the follicles. The shampoo's small particle size allows for 3.5 times more Benzoyl Peroxide to remain on the skin helping to protect against further irritation and damage.
