Hair serum is specifically designed to add shine and smoothness to hair after styling. It contains ingredients such as silicones, oils, or botanical extracts that can coat the hair shaft, helping to reflect light and create a glossy appearance. Additionally, hair serums can help to reduce frizz and enhance the overall look of styled hair, making it a popular choice among stylists and clients seeking a polished finish.

Hairspray primarily serves to hold a style in place rather than add shine, while dry shampoo is intended to absorb excess oil and refresh the hair without the need for washing. Hair mousse is used to enhance volume and texture but does not provide the shine that a serum does. Therefore, the use of hair serum is the most effective method for achieving that shiny, finished look after styling.
