The term 'Ringlet Producer' can be solved by the 6-letter word 'CURLER'. A CURLER is a device used to create curls and ringlets in hair. It is usually heated and consists of a handle with a clamp at the end that holds a cylindrical barrel. The user wraps a section of hair around the barrel and holds it in place until the hair is heated and takes on the desired shape. Curlers are often used to create a variety of hairstyles, from tight ringlets to loose waves.
