TRESemme Pro Keratin Repair Shampoo visibly repairs hair from styling and heat damage with smart Bond Plex technology. This smart system works to smooth and shield hair fibers from within for strong, healthy-looking hair that is protected from future damage. Styling, heat, combing and washing can damage hair and break essential hair bonds, resulting in dull and unmanageable hair. Our smart technology penetrates the hair to construct new bonds and strengthen hair from within. To use, apply a generous amount of this nourishing shampoo to wet hair. Massage gently from roots to end to work into a lather. Rinse thoroughly. Follow with TRESemme Keratin Repair Conditioner. From our origins in salons, we have always been driven by a simple truth: every woman deserves to look fabulous, like they've just stepped out of the salon, without spending a fortune. TRESemmé is dedicated to creating hair care and styling products that are salon quality without the salon price. Great for all hair types, just shampoo in the shower and your hair will feel nourished and ready so that you can take on the day and night with confidence.
