was on my oldest. An outrigger canoe flipped and the outrigger hit my son in the head. Left a 4 inch gash to the skull on the top of his head. Since he's deathly afraid of needles, he begged me to just super glue it instead of going to get staples. It took a day to get the glue to hold together but it finally did. He now has a bald spot in that area but it's a clean scar.
