Recently I had roached my horses main because it was looked so bad.. It was all different lengths and it was a totally different color then his other hair he had. So after I roached it I put MTG on it hopping that it will go back nicer.. And it has been except one part ... I looked closely at it and once strip on his main had like a bald spot with like a couple random hairs and I though it could a fungus problem so I kept putting it on and I bought some miracle water.. but I hasn't seemed to help.. Do you have any ideas what it could be?
Sorry I don't have any photos to show.
