Call me crazy, but I have been cutting my own hair for the past ten years or so. For me, it is quite simple since I do not color my hair; and I tend to keep it one length. Since that is typically the norm for most children, why don't you consider cutting your child's hair?
For every hair cut you do at home, you will save up to $25 since you will not be making a pit stop at the hair dresser. All you need is a spray bottle, a comb, sharp scissors, or a clipper.
