L'Oreal's patented Ceramide R is a unique protective agent which mimics an essential natural component of the hair and reinforces hair's resistance to outside aggressions such as brushing, blow drying and ironing. Ceramide R reinforces hair where it needs it in the cuticle layers. Hair is fortified and has more resilience and cohesion. Hair is less susceptible to protein loss and feels unbelievable smooth from root to end. Moisturizers, panthenol, lanolin and silicone further improve detangling and softness and leave hair with unbelievable shine.
