Milk_Shake Leave-In Treatments are the perfect prep product for a truly stunning and healthy style. Each of these treatments features a key ingredient, paired with Milk Proteins to help leave hair healthy, hydrated, and stronger. Milk Protein has a deeply conditioning and nourishing effect on the hair and provides it with strength and softness. In addition to Milk Proteins, all of these leave-ins also include the Integrity 41 Complex, which uses sunflower seed to provide hair with antioxidants. These antioxidants help to shield and protect hair color vibrancy, leaving strands with color intensity and shine.
