The importance of conditioner on hair systems cannot be underestimated. Conditioner helps the hair “move” more freely as well as untangles matted hair. It allows a comb or brush to move the hair in the desired direction and coats the hair to help strengthen it. BUT do not over condition the hair system. Usually one to two minutes is sufficient. Over conditioning the hair can accelerate hair loss due to the conditioner loosening the hair knot in the foundation. Sometimes over conditioning can cause the hair to mat as well. We are talking about conditioners used in the shower. A good leave in conditioner also helps the hair leaving it with a healthy sheen. Look for one that also has sunscreen to help retard fading.
