OxyMed Treatment is not a shampoo, it's an ultra-soothing medicated rinse formulated to stop itching, control flaking and reduce shedding.  OxyMed contains Alpha Hydroxys, which make this rinse far more effective than any medicated shampoo at relieving seborrhea and other skin problems.  Alpha Hydroxys penetrate the lowermost levels of the skin (tratum corneum) and "clean out" the skin's pores.  Vitamins and Omega 3 Fatty Acid supply nourishment for a healthy skin and coat.
