I was just thinking about how hard to brush the ends of my hair are, and how they seem to stick together. I voted damage and buildup, because it has been a while since I trimmed my hair, and in the past when I have had this problem, shampooing the length has helped. But one shampoo didn't do it when I tried a week or two ago, so I guess I'll try it again and then start looking at what else might help.
