Ellie is 7 months old. The top of her hair is all silver. When people see her they think she is really old. I like her coloring alot But she looks greasey about 3 days after her back. I have spent 50 buck at pet smart tring to find the right shampoo for this hair. I am thinking about getting so silver by jermack (human shampoo) to see if this will help. Does any one know of something great?
