Paul Mitchell’s Bond Rx Professional Treatment contains heat-activated technology which targets these weak, damaged bonds, crosslinking them to fortify and add resilience to the hair fibre. Ceramides within the formulation restore the hydrophobic layer and seal the cuticle, leaving the hair soft and smooth with its natural protective barrier restored from root to tip. This conditioning hair mask exudes a delightful fragrance combining warm notes of Amber, Sandalwood and Vanilla Orchid. Colour safe. Free from SLS, SLES and ALS. Cruelty-free & vegan-friendly.
