Does anyone know how to get medical "super glue" out of hair without cutting it out?

My son had a scalp injury a few weeks ago that couldn’t be closed with stitches, so it was closed up with the medical glue. It worked great on the cut, but now he has these bits of glue left in the surrounding hair that refuse to come out. I don’t want to cut it if I don’t have to because he will have a huge bald spot in a very visible place. Any suggestions?
