I have been able to use cheap children's no-tears detangler from the dollar store with some success to her skin, but it just didn't work as great for her mane or tail (especially not for her tail). The main ingredient in all of the ones that did not work was silicone. I'm guessing this is what she is allergic to.
I'm wondering if there is anyone out there who has had experience with this same problem and has a suggestion for a product geared towards this. I appreciate all of your suggestions ahead of time.
