Salon Pro Hair Food Vitamin E Formula is a lanolin-enriched treatment which repairs and strengthens hair that has been weakened or damaged by chemicals, thermal styling, or even everyday hair grooming. This blend of natural oils, reparative proteins and conditioners penetrates easily into the hair shaft to give it needed moisture and shine. Each strand is strengthened with keratin, the protein which is the building block of hair and Vitamin E which helps quench dry, itchy scalps and helps restore a proper oil-moisture balance to the hair.
