The primary purpose of using a hair serum is to smooth, shine, and protect hair from damage. Hair serums typically contain silicone or other conditioning agents that create a protective barrier around the hair strands. This barrier helps to reduce frizz, enhance shine, and provide a smoother surface by filling in imperfections on the hair shaft.

Moreover, serums often contain ingredients that can protect hair from environmental factors such as humidity, heat damage from styling tools, and UV exposure. This protective quality is essential, especially for people who frequently use heat styling methods or who have hair that is prone to damage or dryness.

While adding volume, holding hairstyles, and promoting hair growth are important aspects in hair care, these functions are primarily served by other products like volumizing sprays, hairsprays, and growth serums, respectively. Hence, the focus of hair serums centers on delivering shine, smoothness, and protection.
