I decided at the end of freshman year to cut my hair to a cute bob, in which the longest pieces were just under my chin. I got 6-8 inches cut off, and it ended up looking great (even though I cried the first time I ran my fingers through my hair!) I started letting it grow back out, but ended up cutting it again at the end of sophomore year because I didn’t like the in-between short/long look, and figured that I could keep it shorter through college and have fun with it before I tried to grow it out.
My hair ended up being a lot healthier too, seeing as I cut half of it off and somewhat started over.
