Is it Just Me?!

So I recently got my hair done. I love it when you go and you get the new color and the hair wash and they do it all cute. Then a week later you see split ends!!!! How is it that I just spent $70 on a cut and a color and I can see a split end on a single hair?! Granted I did say that I just wanted a trim (I am trying to grow my hair back out) but that does not mean you barely do the job. I have shaved more hair off my legs- sorry for those reading this that are grossed out. But I had to make a point. Man, I just needed to vent. I was just hoping that I wasn't the only one that got jipped out of a "real" haircut.
Thanks for letting me clear my head.
