Does hair serum remove frizzy hair?

Yes, a hair serum can visibly reduce frizzy hair. Frizz often occurs when the hair cuticle is raised and the hair absorbs moisture from the air. Serums form a smooth, conditioning layer around the hair, helping to smooth the cuticle. This makes the hair instantly smoother, softer, and more manageable, with less frizz and more shine.

An example of this is the Smooth Operator serum. This serum is specially developed to tame frizz and unruly hair, nourish the hair with ingredients such as vitamin E and plant proteins, and visibly improve shine. The result is smoother, more flexible hair that is better protected against humidity. However, the effect depends on styling and is largely washed out after cleansing.
