How do you do a piggy back perm?

To do a piggyback perm, first, section the hair into two halves: the top and bottom. Start by wrapping the bottom section of hair around a perm rod, then gather the top section and wrap it around the same rod, creating a "piggyback" effect. This technique is ideal for longer hair, as it helps achieve uniform curls throughout. Finally, apply the perm solution, allowing it to process according to the product instructions, and rinse thoroughly.
