Matrix Instacure Build-A-Bond Billion Bond Oil is a professional leave-in hair oil designed to support very damaged, over-processed hair. Infused with citric acid to help reinforce inner hair bonds and amino acids to support the hairs internal structure, the lightweight gel-serum texture smooths through the lengths without a greasy feel. The vegan formula is created to add clean-looking shine, promote the look of stronger strands and help reduce the appearance of split ends, leaving hair feeling closer to the freshness of a recent cut.

Suitable for all hair types, including colour-treated and heat-styled hair, this product fits easily into an everyday haircare routine whenever hair needs extra care. It can be used on damp hair before blow-drying or styling with straighteners, curling irons or diffusers, offering heat protection up to 230240C/450F, and on dry hair to refine the finish and add softness. The result is hair that feels smoother, more manageable and beautifully polished from mid-lengths to ends.
