Ice On Ice is a leave in coat conditioner and finishing spray. Similar to but unlike the old silicon products Ice On Ice is water soluble. Ice On Ice puts a protective barrier on the outside of the hair strand and locks in moisture, it is not oily and Ice On Ice repels dirt, dust, rain, urine from soaking into the coat. Ice On Ice also contains sunscreen. SUNSCREEN - Ice On Ice contains Sunscreen. Sunscreens do not have a long life span, so if you are trying to keep that black coat from bleaching out to red or a short coated breed from sun burned skin you need to spray Ice On Ice on the coat every day. By the way, try Ice On Ice on your own hair, you'll love it!
