A few weeks ago, my mare's mane hair started falling out, strand by strand. I would lose 20 or so strands each time I put her mane through my fingers. It got better for a while; only three or four strands came out in my fingers each time I touched it.
Recently, it's gotten worse again. The floor of the wash rack was full of long mane hairs... What's going on here? Why is she shedding her mane and what can I do to prevent it?
I almost put this in the health section, because it just seems... Abnormal.
