What is a spiral perm technique known for?

The spiral perm technique is known for producing uniform curls by wrapping the hair around a rod in a vertical manner. This method allows the hair to be curled in a way that creates a defined, spiraled shape that is consistent throughout the length of the hair. The vertical placement of the rods encourages the formation of tighter, well-defined curls that cascade down, giving a bouncy and lively appearance.

This technique contrasts with other methods that may create different types of waves or curls, such as loose waves, which are achieved through other perming techniques or tools. Additionally, spiral perms do not focus on enhancing natural texture or straightening curly hair, as their primary objective is to create distinct, uniform curls rather than altering hair characteristics significantly.
