Wash the tail first then use a generous amount of detangler...a liquid/gel type os better than a spray..it seems to penetrate better...like the oil others are indicating :) The detangler I have found best to date is called Vetrolin Detangler. It makes the hair very slick to the point when I had it on my hands, I kept losing hold of the billet when I was trying to do up the girth; my hands were slippery even though they were dry. If you use a base oil like corn oil, baby oil or olive oil you will need to rewash the tail afterwards or the dust/dirt will really stick and you could be back to square one with tangles.
Once well coated with the detangler, as others indicated, start at the bottom and using your fingers, work the knots. Massage them between your fingers first to loosen them up and then gently pull them apart.
The thing I do with my horse's tail on a daily basis is that I hold up the bulk and let it then fall in smaller sections in a curtain like fashion, brushing from bottom to top, then letting another section go, brushing bottom to top and so on until I get the entire tail done.
