I only very rarely get one of the little knots, and then only when my hair's quite long (below my bra band) and needing a trim.

I've never had the typical split ends except a little bit when I used to use lye-based cream relaxer - over 30 years ago, LOL! Even using that stuff for a few years, I had fewer splits than most of my straighter-haired friends. I was mighty careful with that stuff and didn't color at all, so I'm sure that helped.
