This Matrix Instacure Build-A-Bond Super Sealing Leave-In Balm is a powerful leave-in treatment designed to combat damage, breakage, and frizz, whilst offering heat protection for all hair types. Formulated with strengthening Citric Acid to reinforce damaged hair fibres from within and smoothing Squalane to soften and refine each strand, this balm delivers a silky, salon-quality feel and visibly stronger, smoother hair. Apply a small amount evenly through clean, damp hair, focusing on mid-lengths to ends, then style as usual for optimal detangling and a revived, polished finish
