Chin Strap Beard Shape – Square How to grow – the chin strap beard is one of the shorter beard styles that works well with short hair. A fade would also go well with this beard. Let your sideburns fade gently into a short growth of stubble that moves along your jawline, covering your chin and back. Don’t let the beard extend past the jawline onto your cheek as this will ruin the look. Keep the mustache down to stubble, along with a small, nearly invisible soul patch for added effect.
