Healthy-looking hair is smooth, shiny, strong and soft. As healthy hair becomes damaged, it loses some of its naturally protective layers, so it can look dull, feel rough and become difficult to create hairstyles. Unfortunately hair has no biological mechanism, as skin does, to remedy the damage or “heal.” The good news is that the advanced technology in many of today’s hair care products can temporarily provide weathered, damaged hair with the look, feel and behavior of healthy looking hair.
