Hi WavyNWild, I am coarse like you and actually grew my hair for 7 years without any haircuts except 3 times "dusted" the ends to even them up a little (less than 1/4 inch trim) and never got any split ends. Split ends are exceptionally rare for me.

I think if your hair is coarse and resistant it's less prone to splitting, and this is normal. If you take good care of it on top of the natural texture being strong, you probably won't get any split ends at all.
