Olaplex N°.0 Bond Building Treatment is a hair care product designed to strengthen and improve the appearance of hair. Utilizing patented bond-building technology, this formula works to reconnect broken disulfide bonds within the hair structure caused by chemical processing, heat styling, and environmental factors. As the initial step in the Olaplex system, it is intended to be used before No.1 and No.2 treatments to enhance their overall effectiveness. Suitable for all hair types, including colored, fine, or coarse hair, this vegan treatment helps reduce frizz, split ends, and breakage while increasing shine, softness, and manageability. To use, apply to dry hair for ten minutes before shampooing. It is recommended for weekly use as part of a regular hair care routine to support hair strength, elasticity, and health without the use of harsh chemicals.
