I use to get split-ends all the time but I think this was because of how dry my hair was (daily sulfate use) and almost daily straightener use. In fact my 'wake up' that I needed to take better care of my hair was when I went to the salon and the hairdresser had to cut of 6 whopping inches because the hairs had split and it had tracked up my hair shaft and broken it off un-evenly :/

Now today (1.5 yrs curly girl) I haven't had split ends since that time. I check it constantly (I might be a bit paranoid) but my hair has never been more healthy or as strong sooo no split ends for me so far.
