Redken Color Extend Shine Enrich Protective Shine Serum is a hair serum designed to protect and enhance the color of color-treated hair. It contains a blend of silicone, vitamin E, and UV filters that help to seal the hair cuticle, prevent color fading, and provide protection against environmental aggressors such as sun and pollution. The serum also adds shine and smoothness to the hair, making it look healthier and more vibrant. To use, apply a small amount of the serum to damp hair before styling. You can also use it on dry hair to add shine and control frizz. It is recommended for use on color-treated hair and is suitable for all hair types. However, it is always best to do a patch test before using any new hair product, especially if you have sensitive skin or allergies. This is a unisex product. Comes in liquids form.
