don't be fooled into thinking you need to cut her hair to rid the split ends. Simply take a comb through and trim the flyaway ends. Plenty vids on youtube if you want to take a look. We use pretty much the same for dd's hair and she has some split ends. I think it just happens over time no matter what you use. Smoothing the hair shaft may help appearances though. Have you tried a little coconut oil then rinse it out.
