Cutting hair yourself can save you lots of money. I can't say that I enjoy it, but I do enjoy the savings. I only have one child at home now, so sometimes I will get lazy and give her a coupon to get it cut for 5-7 dollars, but they do a good job. My husband, on the other hand, likes me to cut his hair. The money we save can go for a date night that week or be saved towards something we really want. When we had 5 kids at home, it was really worth it to cut everyone's hair myself.
If you don't feel comfortable with your hair cutting skills, find a friend who knows how to and barter. I think bartering should make a come back. Both parties save money and both get something they want if done properly.
