Final answer:
The levels of observation in hair design analysis include the macroscopic, microscopic, and molecular levels.
Step-by-step explanation:
The levels of observation in hair design analysis include:
- Macroscopic level: This level of observation focuses on the overall appearance and characteristics of hair, such as its color, texture, and style.
- Microscopic level: At this level, hair is examined under a microscope to analyze its structure, including the cuticle, cortex, and medulla.
- Molecular level: This level involves studying the molecular composition of hair, including the proteins and other molecules present.
Therefore, the correct answer is option 4) All of the above.
