Which technique is NOT one of the four techniques of women's hairstyling?

Painting is not considered one of the four primary techniques of women's hairstyling. The four traditional techniques include wet setting, hair wrapping, styling with a blow dryer, and thermal styling. Each of these techniques involves specific methods used to shape, create texture, and set hairstyles effectively.

Wet setting utilizes the moisture in hair to create curls or waves, allowing the hair to dry in a certain manner to maintain those styles. Hair wrapping involves carefully wrapping the hair in a specific way to achieve a smooth and sleek look, often for maintaining straight styles. Styling with a blow dryer is a technique that uses heat and airflow to shape and style hair, providing flexibility and versatility.

Painting, in a hairstyling context, typically refers to a coloring technique rather than a method of styling hair. While color application can enhance a hairstyle, it does not fall into the same category as the various methods used to style or shape hair. Therefore, painting stands apart from these foundational hairstyling techniques.
