A deep conditioning treatment is specifically designed to provide intense moisture and nourishment to the hair, helping to repair damage and improve overall hair health. Hydrolyzed proteins are a key ingredient often found in these treatments because they work by penetrating the hair shaft, strengthening the hair from within and enhancing its elasticity. This repair process helps to rebuild the protein structure of the hair, making it less prone to breakage and damage.

Essential oils, while beneficial for adding fragrance and sometimes providing light moisture, do not have the same strengthening properties as hydrolyzed proteins. Alcohol can actually have a drying effect on hair, stripping away moisture, which is counterproductive to the goal of deep conditioning. Sulfates are commonly found in shampoos and other cleansing products; they can be harsh and drying, which is not suitable for a conditioning treatment that aims to hydrate and nourish the hair.

In summary, hydrolyzed proteins play a vital role in deep conditioning treatments by reinforcing the hair's structure and providing essential moisture, which is why they are commonly included in the formulation.
