Final answer:
The last step of creating hair coils involves unraveling the coils after the hair has been set into the desired shape. Temporary waves are formed by water molecules affecting hydrogen bonds in the hair, whereas perms use chemicals for a lasting style.
Step-by-step explanation:
The final step in the process of creating hair coils is unraveling the coils. When we talk about temporary hair waving, water molecules enter the keratin strands when the hair gets wet, which disrupts some hydrogen bonds. As the hair dries, new hydrogen bonds form, allowing the hair strands to temporarily maintain the new curl. For a more permanent solution, perms apply chemicals to the hair, which is then wrapped around forms to produce the desired hairstyle. The hair can be either curled or straightened during this chemical reaction.
The final step in the process of creating hair coils is unraveling the coils. After coiling the hair, applying gel, and drying the hair, the last step is to carefully unravel the coils to reveal the desired hairstyle.
