^ Agreed, :)
But usually what i do with my horses tail, is i layer it kind of, and trim it, Like i take the tail and go close to the butt and cut in a slant, kind of like doing angled bangs for people ! it looks really nice when they move imo :)
( makes it harder when you want to braid etc though)
But i would get some spray in detangler and conditioner, with some stuff that you can spray which makes the horse shinyer :)
But usually the detangler and conditioner leave in spray look great.
As said above you dont want to wash the tail to often
