Hair gel or mousse are commonly utilized for setting hairstyles because they provide hold and structure to the hair. These products contain polymers that create a lightweight film around each strand, helping to maintain the desired shape and style throughout the day. When applied, hair gel can give a firmer hold, making it suitable for styles that require more definition, while mousse offers volume and a lighter touch, making it ideal for natural flow and bounce.

Conditioner primarily serves to moisturize and detangle hair, lacking the properties necessary for maintaining a lasting style. Hair spray does offer hold, but it is generally used as a finishing product after a style has been created rather than a setting agent for the styling process itself. A heat protectant is designed to shield hair from damage caused by heat styling tools and does not contribute to styling or setting a hairstyle. Thus, gel or mousse stands out as the appropriate choice when it comes to setting hairstyles.
