Keratin hair serums are a type of hair care product designed to help strengthen and nourish hair. These serums contain keratin, a protein that is naturally found in hair, which helps to rebuild and repair damaged hair. Keratin hair serums are available in a range of different formulations, each designed to address specific hair concerns, such as frizz, breakage, and dryness. They are typically applied to damp hair before styling, and can also be used as a leave-in treatment for added hydration and protection. For those looking to improve the health and appearance of their hair, keratin hair serums can be a useful addition to their hair care routine.
