hmm not to sure. I wash her mane once a week but deep condition it so its never dried out. I'll have to take a took at the bottle and see, I know cowboy magic has a lot of natural silk protein in its products and I believe SPF protection and such. I also use the Equss? sp? line, and thats amazing shampoo and conditioner totally ALL natural.
She is a stink to keep clean, but I'm a freak about stains!
