I have talked with a few horse people that come into my work about getting the horse hair in the leghtens needed for the braids and all have said the same thing, to get what you need to do this your are talking about $300-$500+ to do it. The blond horse hair alone can be $250+ just by itself.
Unless I go and sneek into a pasture and cut off part of a horses tail, it is not gonna happen for me on the horse hair, I can't see spending that much on it.
