Yeah, seems like I was too naive here…
Most horsehair comes from slaughtered horses. Hair for bows comes from tails of horses in cold climates, and is sorted by size. It comes primarily from stallions and costs $150–$400 per pound because of the sorting needed to extract long hairs. Mongolia produces 900 tons of horsehair per year.

I didn’t mean to justify horsehair products but seriously thought that you wouldn’t need much of it to produce a couple of violin bows and that it sure won’t hurt the horses. But man… 900 fucking tons and - as you predicted - horses are mostly killed.
And apparantly there’s also a practice to pull out the hair and whiskers rather then cutting it off. And this is apparantly not even done to get the hair but to improve the horse’s look.
