One of the strongest bonds occurring in nature, Disulphide bonds link hairs protein structures and are essential for elasticity and strength. The high-in-cysteine amino acid complex in BOND conditioner caters to creating these bonds, adding resilience, while a near-clinical level of ProVitamin B5 penetrates deeply, adding essential moisture. Excellent for all hair types, BOND conditioner is especially effective on dry, damaged, or super curly hair. Formulated without sulfates (SLS/SLES), parabens, or dyes.
