Let me preface this with: I am in no way a professional barber. I am just cheap.
I cut my family’s hair. I even trim my own bangs, though I haven’t lately. The woman who cuts my hair (3-4 times a year, whether it needs it or not) gets a little frownie line between her eyes when she sees I have taken the scissors to my hair. I figure it is safe to say I am not exceptionally good at it.
