In my area kids cuts are about $12. Clipper cuts are $8 and bang trims are $4. So that means for my two older ones to go once every 6-8 weeks it's $24 before the tip. I don't know about you but I can think of a lot of things to do with $24 that does not involve waiting in a salon with my brood of kids. I just did my oldest two tonight and I think of it like earning $24 in about a half an hour.
Here are a few YouTube videos on kids hair cut how two's that I thought were good:
Boys longer scissor cut (non clipper). Also great ideas on keeping your child still and tools you might want to invest in.
Clipper cut ( A little boring but informative.)
Girls Cuts and Bang Trim ( There is 20 second ad before the video, bummer but great video.)
