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?
My mare's (roached) mane has a similar thing, if it's what I'm thinking it is. She has a chunk about 6 inches long on the bottom half of her mane where her mane is only about half thickness. The half that isn't hair is just a "naked" spot that she has a few mane hairs growing out of but other that that, it's just skin. My theory is that maybe at some point in her life, she rubbed there SO much that she manged to kill all the hair follicles. But I really have no idea what happened.
Here's a picture (from a year ago) where you can kind of see it, I couldn't find a better one... It's that dark chunk on the lower half of her neck...
It's probably an overdose of MTG. If you put to much on at once, it can drown out the hair and cause it to fall off. A while ago everyone at my barn was using the stuff and using a lot of it, and then the horses mane started falling out. Just cut back of stop using it all together and it should come back, if it's the same thing that happened at my barn.
