Question on pasture braids
So, I braided my gelding's mane into about 7-8 pasture braids, knowing that they are supposed to help keep the mane tangle free so I don't have to brush it so often, and that they are supposed to prevent breakage. I left the braids in for maybe 3-4 days, then took them out to re-braid since they were all shaggy looking. When I did this and finger combed it through, a LOT of hair came out. Is this normal? Do horses lose so many hairs a day like people do, and is this where all the hair came from, or is it from breakage and from it getting pulled out? I feel like I'm ruining his mane, and wonder if I'm doing something wrong?
Thanks in advance for your help :)
