Question: 1 / 400

What is the function of a hair serum?

To promote hair growth

To add shine and reduce frizz

The function of a hair serum primarily involves adding shine and reducing frizz. Hair serums typically contain silicones and other smoothing agents that coat the hair shaft, providing a glossy appearance and taming flyaways. This creates a protective layer that enhances reflection of light, giving the hair a vibrant shine. Additionally, by smoothing the hair cuticles, serums help manage frizz and create a sleeker look, especially in humid conditions.

While promoting hair growth, cleansing the scalp, and strengthening the hair are important aspects of hair care, they are not the primary functions associated with hair serums. Instead, those functions are typically addressed by other products such as hair growth treatments, shampoos, and conditioners designed specifically to enhance moisture retention and structural integrity of the hair.
