Olaplex No.3 and No.8 Duo

new No.3: No. 3 Hair Perfector is a concentrated treatment thatstrengthens the hair from within, reducing breakage and improving its look and feel. It is not a conditioner, it's an at-home treatment that contains the same active ingredient found in all professional Olaplex products. Created by two of the top PhD's in chemistry and materials science, Olaplex products feature first-of-their-kind, patented, bond-building technology, which relinks the broken disulfide bonds caused by chemical, thermal, and mechanical damage to the hair. This formula is made to work with every hair type,providing real, structural repair that works from within. No.8: AllOLAPLEXproducts contain ourpatented bond-building technology, strengthening fragile bonds with every step of the routine for thehealthiest hair possible. That same revolutionary technology is now infused in an at-home mask treatment for all hair types. All hair is unique, but all damage is the same. Whether it's from chemical processes, heat and styling, ponytails and brushing, or a harsh environment; damaged hair means damaged bonds. The result is hair that is dry, dull and less than manageable.
