For full, frizz-free hair that stays for days, try RE:UNITE Silky Smooth System, 3-step hair smoothing system that dramatically tames, strengthens, and repairs hair at home or in the salon. Its results are similar to in-salon keratin treatments but without all the damage and the smell. Unlike traditional keratin treatments, that leave hair smooth and often flat and dry, the RE:UNITE Silky Smooth System is actually good for your hair. It smooths, strengthens, and repairs, plus creates volume, all while leaving hair smelling absolutely amazing.
