Final answer:
Molly decided to dye her hair all the colors of the rainbow, a decision reflecting a significant commitment to maintaining a colorful and vibrant hairdo. The correct option is 3.
Step-by-step explanation:
Molly decided to dye her hair all the colors of the rainbow, embracing the full spectrum of visible light. Hair coloring has become an immensely popular way to make a fashion statement, with a significant percentage of individuals experimenting with different shades and tones, as seen in the statistics from Copenhagen.
Hair dye can be either permanent or semi-permanent, with the former chemically altering the structure of the hair until it is cut away.
It's important to recognize that even permanent hair color doesn't stay the same indefinitely; natural color persists longer while artificial color fades quickly. Molly's decision to dye her hair in such a vibrant way might require regular maintenance to keep the colors bright and prevent fading, demonstrating the commitment often needed when changing hair color to something as bold as the shades of a rainbow.
