Know the hair you have to get the hair you want. Your hair's starting point: color-treated or highlighted. When hair is color-treated, it changes at the structural level. Its natural light-reflective surface becomes uneven. This is one reason why your hair can appear dull over time. Pantene Pro-V innovation: Pantene's Color Preserve Shine shampoo and conditioner system features micro-polishers. The shampoo helps preserve your brilliant color, and the conditioner smoothes and refinishes hair's outer layer. So your hair reflects light and your color shines brilliantly.
