Keratin-based hair products are formulated to strengthen and coat the hair shaft, which is essential for enhancing the overall health and appearance of hair. Keratin is a fibrous protein that is a fundamental component of hair, and when used in hair care products, it helps to fill in gaps and reduce porosity in the hair. This reinforcement provides structural support, making hair more resilient to damage from environmental factors or styling practices.

These products often create a protective barrier around each hair strand, which helps to maintain moisture levels and can lead to shinier, smoother hair. Additionally, the coating effect can also help reduce frizz and improve manageability, leading to a polished finish.

Keys to effectiveness include the ability of keratin to bind to the hair cuticle, providing both strength and a layer of protection without altering the natural color or removing existing conditions, such as dandruff or adding volume. This characteristic makes keratin-based products particularly popular in the realm of hair treatments aimed at repairing and improving hair health.
