is it wrong to cut your hair?

I had the great opportunity to read through Leviticus this week, and I was very shocked by some of the things that I had read. I didn't know their were so many rules in this book. The one verse that really through me for a loop was found in chapter 19 verse 27: "You shall not round off the side growth of your heads and  not harm the edges of your beard." This stuck out to me because I love getting my haircut , and trim my beard when I can so is that wrong according to this verse? Hopefully throughout this blog I come to the conclusion of why is it wrong to cut your hair?
