This lightweight shampoo is infused with a blend of naturally-derived proteins and poly-sugar to revive and add body to thin and lifeless hair. Kiehl’s chemists have utilized the latest in haircare science—a volumizing complex that coats hair to impart a healthy, thicker appearance and vitality—and combined it with the long relied upon benefits of Rice and Wheat Proteins to create fullness and body without stripping hair of natural lipids.
