The use of hair serum or oil as a finishing product for shine is widely recognized among cosmetology professionals. This type of product is specifically formulated to add a glossy finish to the hair, enhance its overall appearance, and improve manageability. Hair serums and oils typically contain ingredients that help smooth the cuticle, reducing frizz and creating a sleek look while reflecting light, which contributes to a shiny appearance.

While hair gels, hairsprays, and leave-in conditioners serve important functions in styling and maintaining hairstyles, they do not primarily focus on adding shine. Hair gel is often used for hold and structure, hairspray is primarily designed for setting styles in place, and leave-in conditioners are great for moisturizing and detangling but not specifically targeted towards enhancing shine. Thus, hair serum or oil is the most appropriate choice for achieving that shiny finish after a styling service.
