ProShine is a foaming shampoo/conditioner that is made using a 500 year old Welsh recipe that is saponified in a brewing. The shampoo deep cleans and has a slightly acidic pH. To that, Keys adds essential oils to condition the skin and hair. ProShine has anti-allergy properties to reduce skin itching and hot spots. The benefits most noted by groomers and show dog handlers is how it cleans and conditions the hair in one step. Light colored and white dogs experience brighter and whiter hair without using chemicals. What they really love is how fast ProShine rinses and how fast the dog dries. ProShine was originally developed for a breeder who wanted a chemical-free dog shampoo that would produce a lustrous coat that shone without using silicone or dimethicone. Her dogs had developed itching and scratching from the traditional detergent-based sulfate shampoos and conditioners that contained silicone derivatives. Keys developed ProShine to deep clean naturally, using essential oils for the shine and providing fast rinsing that is five to six times faster than conventional detergent based shampoos.The result is a brighter coat, no chemical irritation, and a natural luster that is noticeable. Simple pharmaceutical-grade ingredients that work!
