Caviar Repair Rx Split Ends Mend is clinically proven to reduce split ends by 93% for healthier, stronger hair that shines. The quick-absorbing formula also helps control frizz without weighing hair down while strand-building proteins fill in gaps and tears in your hair's cuticle layer to restructure and strengthen strands and prevent future breakage. Its blend of marine botanicals provides exceptional moisture, while an age-control complex addresses natural, chemical and environmental aging. Caviar extract and vitamin C help smooth hair and increase shine while locking in brightness.
