What is the primary purpose of repair formulas?

The primary purpose of repair formulas is to penetrate the cortex and temporarily reconstruct the hair. These formulas are designed to address damage that occurs to the hair structure, often resulting from chemical treatments, heat styling, or environmental factors. By penetrating deeply into the hair shaft, repair formulas work to restore strength and improve the integrity of the hair.

The effectiveness of these products lies in their ability to work at the molecular level, where they can help to rebuild broken bonds within the hair and provide temporary structural integrity. This is crucial, as most hair damage occurs at the cortex level, making it essential for repair products to reach this inner layer to have a significant restorative effect.

While options addressing enhancement of natural curl, moisture retention, and even fragrance can be aspects of hair care products, they do not focus on the critical restorative action that repair formulas provide to rebuild and strengthen damaged hair effectively.
