PREP Deep-Cleansing Chelating Shampoo, formulated to thoroughly prepare the hair for technical services such as coloring, lightening, perming, straightening, and restorative treatments. Its formula effectively removes buildup from styling products, impurities, and trace elements that can hinder the even penetration of active ingredients.

The PREP deep-cleansing shampoo works through a process of chelation, in which unwanted particles and metal ions are neutralized and removed from the hair. This ensures the hair is completely cleansed and prepared for subsequent procedures, leading to more precise and long-lasting results.

The formula of the PREP chelating deep-cleansing preparatory shampoo features a balanced, slightly alkaline pH (7.0 – 7.5), which helps open the hair cuticle. This makes the hair more receptive to technical processes, allowing for better absorption of hair color, lightening products, and restorative treatments.

The PREP chelating deep-cleansing shampoo is ideal for professional salon use whenever maximum hair purity is required prior to chemical or restorative procedures. It eliminates styling product residue, impurities, and traces of previous treatments—all of which can create a barrier on the hair and compromise the final result.

The PREP chelating deep-cleansing preparatory shampoo serves as a versatile tool in the salon, suitable for use before any technical service—including coloring, perming, lightening, straightening, or restorative treatments. Preparing the hair with this product ensures more vibrant and clean colors, better coverage, and longer-lasting results from the treatments.

When used in combination with the PREP mask, the PREP chelating deep-cleansing preparatory shampoo helps achieve even better results— more intense colors, longer-lasting treatments, and healthier hair.

Thanks to its effective yet balanced formula, the PREP chelating deep-cleansing shampoo provides a thorough cleanse without weighing the hair down, leaving it feeling fresh, light, and fully prepared for the next step.

Created with care for both hair and the environment, the product contains 92% naturally derived ingredients and is 97% biodegradable—a modern, responsible solution for professional use.

When used correctly, the PREP chelating deep-cleansing shampoo ensures optimal hair preparation, enhances the effectiveness of subsequent treatments, and delivers superior, cleaner, and longer-lasting results.
