Final answer:
Different types of curls, such as spiral, loose, tight, and beach waves, can be achieved via temporary waving. Temporary waving involves the interaction of hair with water, disrupting the hydrogen bonds in the keratin strands. The hair then dries into a new shape or curl.
Step-by-step explanation:
Different types of curls include 1) Spiral curls, 2) Loose curls, 3) Tight curls, and 4) Beach waves. These types of curls can be achieved through permanent or temporary waving. In the case of temporary waving, the hair undergoes a series of changes due to the interaction with water molecules. When wet, water molecules disrupt the hydrogen bonds in the keratin strands and allows the strands to slip past each other. A new shape is formed during drying as new hydrogen bonds emerge. The hair can maintain this new shape, or curl, temporarily. This process is what allows for temporary waves or curls to be created.
