Healing is just as important on the outside as it is on the inside. Healthy hair doesn’t just happen from the inside out, nor from just a healthy scalp. You must heal from the outside as well. The surface of the hair is the cuticular layer. It is what we see and what gives the appearance of healthy, shiny, quality hair. A complex of B Vitamins seals the cuticular layer. Prodew 500 works the internal and external shaft. Replenish and fill the cuticle with moisture and strength, leaving the hair healed, promoting shine and enhanced manageability.
