If you need to repair a head cut and can’t get to the doctor, this a neat little trick. All you need are two things: a cut on the scalp and hair.
The hair has to be at least an inch or two long and has to surround the head cut. You twist hair strands on both sides of the cut, cross them over the cut to close it, and glue down your masterpiece. Repeat the process along the cut from one end to the other.
Actually, some doctors use this procedure in the office, especially on kids. I don’t. It’s not that I’m cruel. It’s just, I’m afraid the child might pick at it enough to unstick the hair. But, in a bind, it’s a great little trick. If you have some strong string, like dental floss, you can tie it around the strands where they cross. That way, you don’t have to depend completely on the glue.
