Which type of product is used to add shine to the hair?

Gloss or shine serum is specifically formulated to enhance the shine of hair and create a polished, glossy appearance. These products typically contain ingredients such as silicones or oils that coat the hair shaft, reflecting light and giving it a lustrous look.

While hair gel is used primarily for providing hold and control to hairstyles, it does not necessarily contribute to shine; in fact, it can sometimes create a dull appearance if it dries out. Hair mousse is designed to add volume and body to the hair, and while it can improve the overall texture, it isn't specifically aimed at enhancing shine. Leave-in conditioners help with moisture and manageability but are not primarily focused on shine, although they may provide some.

Therefore, for the purpose of adding shine specifically, a gloss or shine serum is the most appropriate product choice.
