"The first thing is, don't get big scissors," Atkin says. "Get little cuticle-nipping scissors from CVS – you don't have to spend a lot of money – and get a good small-tooth comb." The important thing to remember is that small scissors minimize the risk of big mistakes because they're easy to handle and they have short blades. They should also be sharp to ensure clean, precise cuts. We did our trimming with mustache scissors, which also did the trick.
