I had a simillar problem and I started a thread about it and had great pics, but I think I deleted the pics from my photobucket. My problem was not taking it out enough. You have to take it out atleast once a week or more in the summer or they will start to break. I also REALLY like the braid in tail bags but you pretty much have to re do it everyday or it will fall out. Since I have been doing this I have seen improvement. Leaving it alone didn't work for me. It just gets so snarly and then you have to take like 2 hours to brush it and make sure you don't pull any hairs out, then you do anyways no matter how careful you are, and then they get snaged on stuff out in the pasture and then if you have a mare, she comes into heat and pees all over it and makes it all gross and so on. lol sorry about my rant.
